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 mm2
Electrical Speci cations, TA = +25° C, Vcc= 5V
Typical Applications
Active Multiplier for X Band Applications:
• Fiber Optic
• Point-to-Point Radios
• Military Radar
The HMC444LP4 & HMC444LP4E 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 5V 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 & HMC444LP4E are
ideal for use in LO multiplier chains allowing reduced
parts count vs. traditional approaches.

The circuit board used in the nal 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
