R F OSCILLATOR AND MODULATOR

摘要

APPLICATION FOR PATENT -of- WILSON E. ALEXANDER -for- RF OSCILLATOR AND MODULATOR An RF oscillator and modulator produces a stable modulated RF signal with a varying voltage source and without the requirement for critical device selection. A bias voltage for the oscillator transistor is provided by diode means at the oscillator output, the bias voltage being commuted to the transistor through the oscillator tuned circuit. Advantageously, the diode means biases a diode modulator connected to the oscillator output and to a modulation signal whereby linear operation of the diode modulator is enhanced.
