General Description
The HMC578 die is a x2 active broadband frequency
multiplier utilizing GaAs PHEMT technology. When
driven by a +3 dBm signal, the multiplier provides
+17 dBm typical output power from 24 to 33 GHz.
The Fo and 3Fo isolations are >25 dBc and >36
dBc respectively at 28 GHz. The HMC578 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
-132 dBc/Hz at 100 kHz offset helps maintain good
system noise performance.
