HMC385LP4E is a GaAs InGaP heterojunction bipolar transistor (HBT) MMIC VCO with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifier. Covering 2.25 to 2.5GHz, the VCO’s phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator’s monolithic structure. Power output is 4.5dBm typical from a single supply of 3V at 35mA. The voltage controlled oscillator is packaged in a low cost leadless QFN 4x4 mm surface mount package. This low noise MMIC VCO w/buffer amplifier is used in wireless infrastructure, industrial controls, test equipment, military.
