General Description
The HMC388LP4 & HMC388LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs
with integrated resonators, negative resistance dev-
ices, varactor diodes, and buffer amplifiers. Covering
3.15 to 3.4 GHz, the VCO’s phase noise performance
is excellent over temperature, shock, vibration and
process due to the oscillator’s monolithic structure.
Power output is 4.9 dBm typical from a single supply
of 3V @ 39mA. The voltage controlled oscillator is
packaged in a low cost leadless QFN 4x4 mm surface
mount package.
