General Description
Features
Functional Diagram Output Power: +6 dBm
Sub-Harmonic Suppression: >25 dBc SSB Phase Noise: -136 dBc/Hz Single Supply: +5V@ 68 mA
24 Lead 4x4 mm SMT Package: 16 mm 2
Electrical Specifi cations, T A = +25° C, Vcc= 5.0V
Typical Applications
Active Multiplier for X Band Applications:? Fiber Optic
? Point-to-Point Radios ? Military Radar
The HMC444L P4 & HMC444L
P4E are active
miniature x8 frequency multipliers utilizing InGaP GaAs HBT technology in 4x4 mm leadless surface
mount packages. 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 HMC444L P4 & HMC444L P4E are ideal for use in LO multiplier chains allowing reduced
parts count vs. traditional approaches.

Evaluation PCB
[1] Reference this number when ordering complete evaluation PCB [2] Circuit Board Material: Rogers 4350
The circuit board used in the fi nal application should be generated with proper RF circuit design tech-niques. Signal lines should have 50 ohm imped-ance 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.
