Abstract :
Quasi-monolithic Ka-band voltage control oscillators (VCOs) have been developed based on 0.2 μm pseudomorphic AlGaAs/InGaAs/GaAs low noise HEMT technology. The designed VCO incorporates a PM HEMT, a Schottky diode, matching network and bias circuit. An output power of 10 mW at 26 GHz was obtained. A frequency of 26.86 GHz with 340 MHz of tuning bandwidth and 37 GHz with 160 MHz of tuning bandwidth have been measured. The chip size is 2.5 mm×3.5 mm. This is the first report of a quasi-monolithic Ka-band VCOs using pseudomorphic AlGaAs/InGaAs/GaAs HEMTs in China
