HMC391LP4 / HMC391LP4E

The HMC391LP4(E) is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. Covering 3.9 to 4.45 GHz, the VCO's phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator's monolithic structure. Power output of HMC391LP4(E) is 5 dBm typical from a single supply of +3V @ 30mA. The voltage controlled oscillator is packaged in a low cost leadless QFN 4x4 mm surface mount package.
