Part details & applications

The HMC448LC3B is a x2 active broadband frequency 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.
