Description

The HMC431LP4 is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO with integrated resonator, negative resistance device, varactor diode, and buffer amplifi er. The VCO's phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator's monolithic structure. Power output is 2 dBm typical from a 3.0V supply voltage. The HMC431LP4 voltage controlled oscillator is packaged in a low cost leadless QFN 4 x 4 mm surface mount package.
