Functional Diagram
General Description
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.

List of Materials for Evaluation PCB 112697 [1]
The circuit board used in the final application should
be generated with proper RF circuit design tech-
niques. Signal lines should have 50 ohm imped-
ance while the package ground leads and exposed
paddle should be connected directly to the ground
plane similar to that shown. The evaluation circuit
board shown is available from Hittite upon request.
