ABSTRACT:
This invention relates to a circuit for switching a voltage controlled RF oscillator between two preset variable frequencies and simultaneously imposing frequency modulation about the selected center frequency. A frequency modulation signal is fed to a stabilized amplifier chain consisting of a low level amplifier, a high level amplifier and a feedback network. A switching network allows the output of the feedback network to be changed as a function of the frequency selection input. An isolated input is provided for the injection of frequency modulation.
