DIGITALLY TUNED STRIPLINE OSCILLATOR

摘要

A digitally tuned microwave microstrip oscillator is disclosed. The oscillator includes a resonant section of stripline having a Gunn diode connected between the stripline and ground plane at a low impedance point and having one or more tuning capacitors connected via p-i-n diodes between a high voltage portion of the stripline resonator and the ground plane. Means are provided for selectively biasing one or more of the p-i-n diodes to a conductive state for switching one or more of the tuning capacitors across the resonant stripline for digitally tuning the resonator and oscillator in discrete frequency steps according to the switched condition of the diodes.
