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.
