General Description
The HMC445LP4 is an active miniature x16
frequency multiplier utilizing InGaP GaAs HBT
technology in a 4 mm x 4 mm leadless surface
mount package. Power output is +7 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 -130 dBc/Hz at
100 kHz offset helps the user maintain good system
noise performance. The HMC445LP4 is ideal for
use in LO multiplier chains allowing reduced parts
count vs. traditional approaches.
