Functional Diagram
General Description
The HMC532LP4 & HMC532LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs
with integrated resonators, negative resistance
devices, varactor diodes, and buffer amplifiers.
Covering 7.1 to 7.9 GHz, the VCO’s phase noise
performance is excellent over temperature, shock
and vibration due to the oscillator’s monolithic struc-
ture. Power output is +14 dBm typical from a single
supply of +3.0V @ 85 mA. The voltage controlled
oscillator is packaged in a leadless QFN 4 x 4 mm
surface mount package.
