General Description
The HMC389LP4 & HMC389LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs
with integrated resonators, negative resistance
devices, varactor diodes, and buffer amplifiers.
Covering 3.35 to 3.55 GHz, the VCO’s phase noise
performance is excellent over temperature, shock,
vibration and process due to the oscillator’s mono-
lithic structure. Power output is 4.7 dBm typical from
a single supply of 3V @ 41mA. The voltage controlled
oscillator is packaged in a low cost leadless QFN 4x4
mm surface mount package.
