PERFORMANCE AND APPLICATIONS OF NOVEL TUNABLE OSCILLATORS UTILIZING

The EG performance of novel tunable voltage-controlled, injection-locked and dielectric resonator oscillators utilizing focused-ion-beam-implanted (FIBI) Gunn-effect devices is reported for the fist time. By varying the bias voltage across the device a frequency tuning range from 5 to 25 GHz was achieved, which is the widest band exhibited to date by a single FIBI Gunn oscillator.
