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.

SMT GaAs HBT MMIC x8 ACTIVE FREQUENCY MULTIPLIER, 9.9 - 11.2 GHz OUTPUT Evaluation PCB
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.
