Abstract

Monolithic wide-bandwidth low-phase-noise voltagecontrolled oscillators (VCOs) using 2-?m InGaP-GaAs heterojunction bipolar transistor (HBT) technology are presented in the paper. The tuning range of the VCOs are 28.0 to 34.0 GHz and 33.8 to 39.1 GHz, with a phase noise of -100.7 and - 103.8 dBc/Hz at 1-MHz offset from the carrier.The overall dc power consumption of the differential-output VCOs is 85 mW with a supply voltage of -2.5 V. The VCOs feature wide tuning range and low phase noise at the same time, with a figure of merit (FOM) of -176 and -171 dB. These are the first Ka-band VCOs with wide tuning bandwidth using commercial GaAs HBT process.
