= +25 C, Vdd1, Vdd2 = +5V, 3 dBm Drive Level
Typical Applications
The HMC578LC3B is suitable for:
Clock Generation Applications:
SONET OC-192 & SDH STM-64
Point-to-Point & VSAT Radios
Test Instrumentation
Military & Space
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.
High Output Power: +15 dBm
Low Input Power Drive: 0 to +6 dBm
Fo Isolation: >20 dBc @ Fout= 28 GHz
100 KHz SSB Phase Noise: -132 dBc/Hz
Single Supply: +5V@ 81 mA
