General Description
The HMC448 die is a x2 active broadband frequency
multiplier chip utilizing GaAs PHEMT technology.
When driven by a 0 dBm signal, the multiplier
provides +11 dBm typical output power from 19 to
25 GHz. The Fo and 3Fo isolations are >22 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 HMC448
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. All data
is with the chip in a 50 ohm test fixture connected
via 0.076mm x 0.0127mm (3mil x 0.5mil) ribbon
bonds of minimal length 0.31mm (<12mils).
