General Description
The HMC449LC3B is a x2 active broadband frequ-
ency multiplier utilizing GaAs PHEMT technology in
a leadless RoHS SMT package. When driven by a
0 dBm signal the multiplier provides +9 dBm typical
output power from 27 to 31 GHz. The Fo and 3Fo
isolations are >25 dBc and >30 dBc respectively at
30 GHz. The HMC449LC3B is ideal for use in LO
multiplier chains yielding a reduced parts count vs.
traditional approaches. The low additive SSB Phase
Noise of -132 dBc/Hz at 100 kHz offset helps maintain
good system noise performance. The HMC449LC3B
eliminates the need for wire bonding, allowing the use
of surface mount manufacturing techniques.
