This is not EMP. It is just a high-power microwave transmitter, made with gallium nitride field-effect transistors. Like any microwave transmitter, it can use a directional antenna. If the antenna is big enough, it can have a narrow enough transmitted microwave beacon to intercept only a single drone. The GaN FETs enable a higher transmitter power at whatever high frequency they are using. At lower frequencies, a 70-kW power was already easily achievable in the past. The higher frequency allows a precise aiming of the microwave beacon with an antenna of reasonable size.
