Typical Applications
The HMC448LC3B is suitable for:
• Clock Generation Applications:
SONET OC-192 & SDH STM-64
• Point-to-Point & VSAT Radios
• Test Instrumentation
• Military & Space
The HMC448LC3B is a x2 active broadband frequ-
ency multiplier utilizing GaAs PHEMT technology
in a leadless RoHS compliant SMT package. When
driven by a 0 dBm signal, the multiplier provides
+11 dBm typical output power from 22 to 25 GHz.
The Fo and 3Fo isolations are >20 dBc up to 22
GHz. This multi-rate frequency multiplier can
be used in the generation of a half rate clock for
40 Gbps systems or as part of a multiplier chain to
generate a full rate 40 Gbps clock. The HMC448LC3B
is also 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 -135 dBc/Hz at 100 kHz offset helps maintain
good system noise performance. The HMC448LC3B
eliminates the need for wire bonding, allowing the use
of surface mount manufacturing techniques.
