摘要
Two pseudomorphic high electron-mobility transistor (pHEMT)-based Ka-Band voltage-controlled oscillators (VCO's), which have exhibited novel close-to-carrier phase-noise properties in conjunction with output powers greater than previously reported heterojunction bipolar transistor (HBT)based oscillators, are presented in this paper, Good low phase noises of at least -70 and -75 dBc/Hz at an offset of 100 kHz around 38 GHz have been measured for the two different VCO designs over reasonable frequency tuning ranges with flat or linear output-power tuning in these ranges. Both designs show a strong dependence between phase noise and tuning-element bias conditions.
