Silicon Carbide(SiC) and Silicon(Si) are both subtracts on which Gallium Nitride TRMs are often placed. GaN-on-Si is low end as its thermal efficiency and bandgap isn't as great as cutting edge GaN-on-SiC based AESA radars. GaN-on-Diamond is the next logical upgrade which thanks to diamond's insane thermal conductivity/efficiency can generate and operate at much higher power for much longer with far less cooling needs(which is limited due to airframe constraints). This translates to far more range and much better resolution in a smaller/tighter package. So a 1000 GaN-on-Diamond AESA radar can generate same/higher power, range and resolution than GaN-on-SiC radar constituting of 2000 GaN-on-SiC TRMs.
Rest I am also tagging in @randomradio, @Picdelamirand-oil & @Stealthflanker, to delve more deeply in this topic as they are the three most knowledgeable people on this topic.

The combination of Silicon Carbide (SiC), Silicon (Si), and Diamond is at the forefront of next-generation radar technology, primarily aiming to maximize power, efficiency, and heat management.
Key advancements involve using Diamond as a substrate or heat spreader for SiC-based devices (often GaN-on-SiC) to handle extreme power densities, with SiC replacing traditional Silicon (Si) for superior electrical performance.

If the naval Rafale order comes, then TEDBF stands cancelled
Its Redundant anyway. Why would you designe a naval fighter when you are operating only two skie jump ACs.
I think TEDBF is first meant to replace Mig29k, and later on will be used for additional carriers. I believe another carrier will construction will start post 2030.
This proves that you still have 36 Rafales and not 35!!!
Officially GOI or IAF won't accept any Rafale loss as it gives strength to traitor Indian Opposition parties to oppose the upcoming 114 Rafale mega deal( plus 31 more for IN); but by now it is an open secret that we indeed have lost BS001. Our official plan to upgrade the remaining 35 jets to F4* standard is a direct proof of that:
Le "super contrat" Rafale F4/F5 signé avec l'Inde le mois prochain. — avionslegendaires.net
Le 11 janvier 2026, par Arnaud. Il y a cinq semaines nous vous révélions que les Indiens se tournaient vers la version la plus évoluée du chasseur français. Aujourd'hui nous sommes en Aéronefs Militaires
www.avionslegendaires.net
"Avions Légendaires" is not a reputable website. In France, people ridicule those who cite Avions Légendaires to support their arguments because the site's author doesn't verify anything and simply believes their opinion is the truth. For example, in the article you cite, they claim the contract for 114 Rafales will be signed in mid-February (the article is dated January 11th), but there is no official statement or document indicating that 35 Rafales will be upgraded to the F4 version. However, there is an official document requesting a proposal for the maintenance, repair, and overhaul (MRO) of 36 Rafales, and 36 Rafales are flying, since the calculation of flight hours over five months, which determines the MRO price, is based on 36 Rafales. If an official Indian organization is willing to pay for 36, it means there are 36.
TEDBF has a too norrow market, and once Rafale M already ordered, it has no chance.
I was always suprised to see India not merging AMCA and TEDBF, as France with Rafale.
