I need to design a class D low power RF amp that I can control the RF output of without tampering with the input signal. I need about 200mW out @ 50 MHz but the input drive is a digital coded pulse train I can't tamper with in any way. I need class D for best efficiency and battery life. How does one go about controlling the output power of such a design?
