I'm curious what foundry in India makes semiconductors for TRM's .

The Uttam could be an actual good baseline for those multiple types of fighters. the Su-30 offers considerable amount of space and cooling potential for the AESA's.
GAETC, SSPL, IISc some other labs offer services to ISRO/DRDO and most plausibly Astra Microwave outsources their production from them, but last I heard they were/or have already opened their own foundry.

Yeah. The potential is great tho i'm kinda wonder on the mass production side of the AESA TRM's for India. The baseline Uttam have about 780 TRM's the Mk-2 have some 912's. mass production will considerably reduces cost if Tejas and "super sukhoi" are to use common TRM's.

Simple back of envelope calculation i did which assumes 9500 MHz center frequency and twitter post depicting Uttam Mk2 antenna, suggest some 87% "fill efficiency" for the Uttam Mk2. Means how much the antenna area is occupied by the TRM's compared to the "empty" area, designers will seek to maximize this to pack as many module as possible.

Assuming the same "fill efficiency" for Su-30 sized Bars.. which have antenna of about 1 meter in area, that would give about possibility to fit 2754 TRM's or about 3 times the amount of Uttam Mk2's. The range factor will scale by 2.29 Times, the cooling load is also scaled by 3 as well as the estimates cost of the radar.

As far as i remember the Uttam mk-1 was credited with about 150 km against a target (afaik stated to be another Tejas prototype) The baseline has about 780 TRM's scaling up to 912 will give range factor of 1.12 or 12% increase in detection range of the same target, brought the range for 912 TRM variant to be about 168 Km.

Flanker sized airframe with 2754 TRM is therefore capable of detecting same target at 384 Km, exceeding the baseline N011M Bars or Bars R by quite amount of margin and would rival or exceed Irbis-E and APG-82.
Engines of Su30MKI would need either some enhancement or replacement
Russia has offered AL-41 engines with increased thrust

I've read somewhere the AL-41 are the worst in stealth class of engines. No composites anywhere, only metal.

I thought Tejas MK2 aka Medium Weight Fighter is a new project but it's not the development of Tejas MK2 started in 2009 and the first flight was scheduled to be on 2018 but now it has been postponed to 2023 and the mass production has to start from 2027-28 onwards

Yes we have been hearing about the AESA-equipped "Super Sukhoi" program for

I think by 2025-26 everything in Su30MKI will be Indian made except for the airframe and engine
It's important to note that the mission of computer of Su30MKI is Indian made
I read some reports saying that India will replace Russian AL-31FP engines of Su30MKI with a derivative of Indian made Kaveri engine but I don't think it's that easy to design an engine for an existing aircraft even if it happens it will happen from 2030 onwards as of now DRDO and HAL are modifying Russian AL-31FP engine of Su30MKI with Indian made components to increase the thrust

I'm quite interested in India's semiconductor progress because I'm not sure where they are sourcing their chips for the Indian military

I've read somewhere the AL-41 are the worst in stealth class of engines. No composites anywhere, only metal.

I would take this chance to clear some misconception on composites

You use composites for weight reduction mainly. For stealth, you still need to Coat it with absorbers as although composites may "have low RCS" They are -Penetrable- by EM wave thus your composite structure may not be visible to radar but -the insides- of your airframe will.

If one wish to reduce RCS with composite then the composite itself have to be designed to absorb or selectively picks what frequency it needs. This called as Radar Absorbent Structure (RAS)

as for the AL-41F1 Su-30's or SM2 used tho.. Stealth are not considered (But also other fighter engine in its class like GE F-132,129 or PW-100 or PW-220/229) therefore it lacks structures one could find in stealth fighter or dedicated engine like F-135 with Rear blocker or Su-57's frontal radar blocker.

India is changing the Russian radar of Su30MKI with Indian one so it basically means that Su30MKI would be able to fire European , Israeli and American weapons like Meteor , Amaraam , Python etc just like LCA Tejas MK1A
