General Description
Features
Functional Diagram
The HMC430LP4 & HMC430LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs
with integrated resonators, negative resistance
devices, varactor diodes, and buffer ampli ers. The
VCO’s phase noise performance is excellent over
temperature, shock, vibration and process due to the
oscillators 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.
Pout: +2 dBm
Phase Noise: -103 dBc/Hz @100 kHz
No External Resonator Needed
Single Supply: 3V @ 27 mA
16mm2 Leadless SMT Package
Typical Applications

The circuit board used in the  nal 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.
