A
= +25° C, Vdd = +5V, 0 dBm Drive Level
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.
Output Power: +11 dBm
Wide Input Power Range: -4 to +6 dBm
Fo, 3Fo Isolation: >20 dBc @ Fout= 20 GHz
100 KHz SSB Phase Noise: -135 dBc/Hz
