A 36GHz Voltage Control Oscillator in GaAs PHEMT Technology

Abstract
36GHz voltage-controlled oscillator is designed and realized in OMMIC’s 0.2μm GaAs PHEMT technology.A fully differential structure is applied in the tunable oscillator.In order to improve the circuit performance,a capacitive-source-coupled current amplifier is used as the active part,and a single-tuned tank as a load.The measurement results show that the center frequency of the VCO is 36GHz and the tuning-range is 800MHz.The phase noise is –98.83dBc/Hz at a 10MHz offset.The chip area is 0.5mm×1mm,and the DC power consumption of the core is 200mW under a single -5V power supply.-
