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.

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 +3V @ 85 mA. The voltage controlled
oscillator is packaged in a leadless QFN 4 x 4 mm
surface mount package.

Evaluation PCB
List of Materials for Evaluation PCB 105706
[1]
The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
