Abstract:
Apparatus is presented for broadcasting an RF signal. This includes a signal divider that receives a composite RF signal and provides therefrom first and second signals each having digital and analog components. A phase extractor receives the first signal and provides therefrom a phase modulated RF signal for application to an amplifier. A gain controller varies the gain of the amplifier in accordance with amplitude variations of the second signal.
