Abstract
A GaInP/GaAs HBT YIG oscillator tunable from 6 to 9 GHz is presented. The HBT used in this circuit has an f/sub T/ and f/sub max/ of 42 and 33 GHz respectively. At 7.8 GHz, the phase noise of the oscillator was -85 dBc/Hz when offset from the carrier by 10 kHz. The phase noise of the present oscillator compares well with the phase noise results of other AlGaAs/GaAs HBT oscillators.<>
