One interesting thing to note on the MiG-35 is that its radome is smaller than that of the MiG-29M2 sold to Egypt and the MiG-29K. Looks like they weren't able to fit the full size AESA into the MiG-29M2 or MiG-29K radome, possibly due to a large back end?
Reality will evade anyone who doesn't look at it properly, courtesy pathetic display and promotion by RAC MiG
Below are some of the units displayed till now. The first one displayed more than a decade ago at Aero India with 680 t/r modules.
The original Zhuk-A or AE was intended to have some 1100 TR Modules. But the cooling requirement is somewhat beyond the MiG-29's capacity. While the one we have now the current scaled back Zhuk-AE does not really meet the expectation.
If I remember correctly, the plan was to have around 1064 t/r modules or 1016 t/r modules. And the Zhuk AESA radar installed on MiG-35 has around 1017 t/r modules on my rough counting. Don't get fooled by the same airframe and radome, its completely different. You can see how much the backend has changed and how far inside the radar has gone inside,

The manufacturer of light class 4 ++ fighter aircraft of the MiG RSK published on its website the official basic flight technical characteristics of the MiG-35 aircraft complex.
As stated in the press service of the corporation, this model is the pinnacle of the MiG family of aircraft. Single MiG-35 and double MiG-35D are created with the widespread use of technology of 5th generation fighters.
Pre-production samples of the MiG-35 aircraft were built by order of the Ministry of Defense of the Russian Federation and are being tested in the interests of the Russian Aerospace Forces. For mass production of fighters, the production and technological base has been modernized and successfully operates, providing the ability to produce aircraft at a high pace and with a high level of quality.
The main flight characteristics of the MiG-35 / MiG-35D:
Crew - 1 or 2 people
Maximum take-off weight - 24 500 kg
Maximum external load - 6 500 kg
Maximum traction - up to 18,000 kgf
Maximum speed - 2 100 km / h
Practical ceiling - 16,000 m
Maximum operational overload - 9G
Maximum flight range - 3,000 km
The fighter is designed to destroy air targets day and night, in simple and difficult weather conditions, as well as the defeat of moving and stationary ground (surface) targets.
The main advantages of the MiG-35 fighter in the corporation were reduced radar visibility, 4-fold redundancy on all control channels, an airborne radar station with AFAR, an optical radar station, and a helmet-mounted target designation and indication system. The aircraft has a modern information-control field of the cockpit with a high level of automation, can use all types of guided and unguided missiles, as well as adjustable bombs.
RD-33MK engines develop 9000x2 kgf thrust on the afterburner and accelerate the aircraft to a speed of 2100 km / h. The fighter has the ability to refuel in flight and can itself act as a tanker.
The full unification of single and double versions of the aircraft in terms of airframe design, on-board equipment complex and functions performed in combination with high-precision weapons allows the MiG-35 fighter to solve a wide range of tasks from gaining air supremacy in the confrontation with fourth and fifth generation fighters,
intercepting modern air attack means and striking with precision-guided weapons at ground and surface targets without entering the air defense zone before conducting air reconnaissance using optical electrons and radio equipment. A fighter can participate in group actions and perform the functions of an air control center for aviation groups.
Armament Composition
At nine points of the external suspension, a wide range of weapons can be located: guided air-to-air missiles of short, medium and long ranges, air-to-surface missiles designed to hit ground (surface) targets, adjustable aerial bombs, unguided missiles, bombs and one-time bomb containers of caliber from 100 to 500 kg, built-in automatic 30-mm gun.

At ARMY 2019 , design Bureau "Vympel" demonstrated its new development – a missile "air-air" which exceeds in its parameters the existing missiles of this class. "Product 180" is a new missile received index K-77M, which will be initially installed on su-57, and in the future may go for export abroad.https://vladimir-krm.livejournal.com/5950713.html
Key Features:
New Dual Pulse Motor
AESA Radar Seeker for Missile
Range of 190 km+ at High Altitude & High Altitude Manouvering Capability
New aerodynamic scheme with X-shaped wings that reduces drag and as a consequence increased range
In the framework of military-technical forum "Army-2019" design Bureau "Vympel" demonstrated its new development – a missile "air-air" which exceeds in its parameters the existing missiles of this class.
"Product 180" is a new missile received index K-77M, which will be initially installed on su-57, and in the future may go for export abroad.
And though the rocket received index K-77M, but it has nothing to do with the missile K-77. The rocket is produced with a new aerodynamic scheme with X-shaped wings that reduces drag and as a consequence increased range.
Rocket in addition to the main wing (2 in diagram below) also added a stationary aerodynamic surface (4) before "driving" (3), which allowed to solve the main problem of all long-range missiles "air-air", namely the ability to maneuver at subsonic speeds. For example, the famous American missile AIM-120 and its recent modernization the AIM-120D have not been able to maneuver at speeds of less than 1200 km/h (while trying to maneuver increased angle of attack, and the rocket began to disintegrate.)
Also the missile is equipped with a double-pulse solid-propellant engine, which allowes high-altitude maneuvering and enables a range of up to 192 kilometers.
In addition, the missile is equipped with inertial navigation system and active radar homing head.
All these changes make the new missile K-77M a truly unique and a real formidable weapon.
Experts pay attention that apparently the Russian defense Ministry are very serious about the project su-57 and to develop this fighter is really unique weapons that have no analogues in the world. We already know that the su-57 would be installed a shorter version of hypersonic missile "Kinzhal" gliding cluster bomb "Drel", and now the missile K-77M. All of these types of weapons created recently and is unique in its characteristics.

Active radar seeker with an active phased array antenna 9B-1103М2.
The illustrations show the layout of the GOS exhibited at the exhibition MAKS-2019 and the booklet given by "Agate".
The latest development of JSC "mnii Agat"
is Designed primarily for advanced missiles "air-air" medium-range missiles, in particular, for the R-77M.
Serial production of the missile already starts, in accordance with the contract signed, the Ministry of defense during the forum Army-2019.
According to the developers, the GOS is also suitable for rockets of class "air-surface".
Having an antenna diameter of only 100 mm, seeker can detect targets with
RCS of 0.003 sq. m at a distance of over 2 km
with RCS of 0.1 sq m (rocket "air-Air" or stealth fighter) - 5 km
with RCS of 5 sq m (conventional fighter) - more than 12 km
Available frequency bands of operation - Ki and Ka.
Weight of GOS is noticeably smaller than its predecessor 9B-1103М (for missiles R-77-1 and RVV-SD) - weight 3.5 kg vs 5.7 kg, 230 mm length 300 mm and diameter 100 mm vs. 150 mm, with comparable characteristics.
However, the main feature of GOS is electronic beam steering antennas and, as a consequence, much more rapid scanning of the airspace in comparison to all predecessors that will be surely helpful for the tasks of missile defense of the carrier, and also in conditions of active electronic countermeasures by the enemy. In creating the AESA seeker for this was also attended by Fazotron-NIIR and NIIP Tikhomirov.

Why would that seeker have a diameter of just 100mm? Especially since its predecessor had diameter of 150mm? What sort of missile is it for, then? It'd be crazy not to utilize the whole width of the R-77 missile body, if it was for R-77 missile family.

The driver is probably the following :
1.Higher frequency. Im curious about Ku-Ka band being mentioned. Probably the original R-77 missile is working in lower frequency (lower Ku or X band) The designer wish to keep the beamwidth thus lower diameter.
2.The desire of lower drag and weight, as smaller radome is smaller drag which contribute to longer range. The seeker also shorter and lighter meaning that more room would be available for larger battery or more propellant.
3.Backfit to other missiles. We might see this seeker proliferate to smaller missiles like Tor or R-73. Or Russia is developing the analogue of CUDA
4.Last but not the least is cost as cost of radiofrequency equipment is a function of frequency. The higher frequency the more the cost as smaller wavelength requires more precision equipment to build the device.
The following Illustrate tradeoff of radar missile seeker wavelength choice. As seen as you go up in frequency, cost climb. The real magnitude however is of course depend on the technology base and amount of production. The graph is from "Radar Homing Guidance for Tactical Missile" It's rather dated (1986) but it clearly illustrate the tradeoff.

Looking at the range figures RCS of 0.003 sq. m at a distance of over 2 km for Ka band seekers.
I think they have opted for higher frequency MMW seeker of 40 GHz Ka band and focused on Anti-Jamming/Burn through capability , Target Imaging with Ka band and all weather capability over Longer range for seeker.
Using K or Ku band as in R-77 might have its limitations in an era where AC carry DRFM jammers and stand off jamming available , Ka band should also be good against LO Target. and using AESA can provide faster Scan Rates and lower side lobes with perhaps lower power needed.
This would also mean R-77M would depend on AC main radar for LR tracking , Guidance and MC updates.
The RVV-BD carries dual seeker of X/Ku Band , R-77 etc carries Ku band seeker and the one for R-77M is a new AESA seeker with Ka Band

Is the one recently displayed even a real flying airframe ?
It is a full scale mockup. But they displayed it poorly, particularly the front fuselage/radome. They copied the same stuff that was on the 2008 MiG-35 demo aircraft.
But that doesn't hide the fact regarding the new Zhuk AESA model displayed. The new version is much more compact and its a larger unit with around 1017T/R modules. Last year it was mentioned the trails were to start in early 2019, so hopefully something might have progressed.

.
The same Radar appears to have been shown back in 2014 designated as FGA-29.
and regarding the quality of the mockup.. i think they also crammed the radar way too deep. giving false impression of compactness. In my view That will leave no space for any edge treatment for radome signature reduction or lobe shaping. The fliying demonstrator of MiG-35 is more likely the "real" way on how the radar supposed to be mounted (i.e antenna part is in radome).
--
Assuming it use same technology from Zhuk-AE and perhaps same modes (but with increased module count instead) It will have about 194-221 Km range against 3 sqm target RCS. About 1.5 times of improvement factor. This basically puts it in league with current generation of modern "medium weight" fighter like Super Hornets and Rafale and this allows use of possibly long range Ramjet missile but i wonder if Russian have any interest left on RVV-AE-PD.

I'd somehow missed this unit until now. But I don't think the radar is crammed inside to give a false impression, the unit as such is compact - both the front and the rear end compared to the earlier displayed model. You can guesstimate the depth of this radar unit from the side view of radome I posted earlier.
I'm not able to get a proper side profile pic or side by side image of the two units, but hope you can make out the difference in the antenna size and the overall size.

That is pretty interesting thanks for that update Austin. https://www.raytheon.com/sites/default/files/news/rtnwcm/groups/public/documents/content/yuse_jed_2015_interview.pdf Pg.26 and Pg.40 most receivers go up to 18ghz. If GaN AESA is applied than there is a possibility that an aircraft can receive and jam VHF and UHF waves. But so far nothing on jamming RF waves higher than 18ghz unless the country has photonic radar receivers.
