Functional Diagram

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).
