General Description
The HMC431LP4 & HMC431LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs
with integrated resonators, negative resistance
devices, varactor diodes, and buffer amplifiers. 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 3V supply voltage. The voltage
controlled oscillator is packaged in a low cost leadless
QFN 4 x 4 mm surface mount package.
