Functional Diagram
General Description
The HMC444LP4 is an active miniature x8 frequency
multiplier utilizing InGaP GaAs HBT technology in a
4 mm x 4 mm leadless surface mount package.
Power output is +6 dBm typical from a 5.0V supply
voltage and varies little vs. input power, temperature
and supply voltage. Suppression of undesired
fundamental and sub-harmonics is >25 dBc typical
with respect to output signal level. The low additive
SSB phase noise of -136 dBc/Hz at 100 kHz
offset helps the user maintain good system noise
performance. The HMC444LP4 is ideal for use in
LO multiplier chains allowing reduced parts count
vs. traditional approaches.

Evaluation PCB for HMC444LP4
The circuit board used in the final application should be generated with proper RF circuit design techniques.
Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be
connected directly to the ground plane similar to that shown. The evaluation circuit board shown is available from
Hittite upon request.
