The Transmit-Receive Multi Modules (TRMM) from Mistral are compact T/R Modules for Phased Array RADARS operating in S-Band. Based on GaN (Gallium Nitride) technology, the TRMM delivers high efficiency in a compact size with a 100W Peak Transmit Power Capability per channel.

Here is a company producing GaN modules for Aesa radars and quoting 100watts peak power.
Like all transistor powered audio amplifiers, that in effect may use similar MOSFET circuits albeit slower than GaN FETs, you do not drive your speakers at full power output of your amplifier. Usually you never go beyond half way line. The transistors work more smoothly, without distress and without creating distortion or heat, at lower power settings.
It is the same with the transmit/receive modules. The power is there if needed. In fact pilots are given the freedom to crank up the power when attacking an adversary’s radar or electronic system.
In Burfis, we may have around 2000 T/R modules. 20-30 watts each, it may need 40-60KW power source. In fact if pilots cranks up the power to 60 watt for a short time it may require 120KW power levels. So there should be a good power source available.
A high-gain antenna is particularly good at transmitting signals in a narrow beam whereas a low-gain antenna tends to send it’s signal in a much wider sweep of directions. So to get destructive power, you will still need power. But not as consequentially as you would if you had a low gain module. From that perspective
@Boracetkin has a point.
