Novel decade electronically tunable microwave oscillator based on the distrubuted amplifier

Abstract

The Letter suggests that a microwave distributed amplifier can be used as a decade-wide electronically tunable oscillator by using the output from the idle drain load as the feedback output and differentially varying the bias of the amplifier MESFETs, taken in pairs. CAD techniques predict that this approach should produce a decade tuning range with seven MESFETs in a nine stage configuration.
