Functional Diagram
General Description
The HMC445LP4 & HMC445LP4E are active
miniature x16 frequency multipliers utilizing InGaP
GaAs HBT technology in 4x4 mm leadless surface
mount packages. 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 & HMC445LP4E are
ideal for use in LO multiplier chains allowing reduced
parts count vs. traditional approaches.
