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.
