Functional Diagram
General Description
The HMC577LC4B is a x2 active broadband frequ-
ency multiplier utilizing GaAs PHEMT technology in a
leadless RoHS compliant SMT package. When driven
by a +5 dBm signal, the multiplier provides +20 dBm
typical output power from 27 to 31 GHz. The Fo and
3Fo isolations are >55 dBc at 29 GHz. The
HMC577LC4B is ideal for use in LO multiplier chains
for Pt to Pt & VSAT Radios yielding reduced parts
count vs. traditional approaches. The low additive
SSB Phase Noise of -128 dBc/Hz at 100 kHz offset
helps maintain good system noise performance. The
RoHS packaged HMC577LC4B eliminates the need
for wire bonding, and allows the use of surface mount
manufacturing techniques.
