General Description
The HMC578LC3B is a x2 active broadband frequ-
ency multiplier utilizing GaAs PHEMT technology in a
leadless RoHS compliant SMT package. When driven
by a +3 dBm signal, the multiplier provides +15 dBm
typical output power from 24 to 33 GHz. The Fo and
3Fo isolations are >20 dBc and >30 dBc respectively
at 28 GHz. The HMC578LC3B 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 -129 dBc/Hz at
100 kHz offset helps maintain good system noise
performance. The RoHS packaged HMC578LC3B
eliminates the need for wire bonding, and allows the
use of surface mount manufacturing techniques.
