The HMC578LC3B is a x2 active broadband frequency multiplier utilizing GaAs PHEMT technology in a leadless RoHS compliant SMT package. When driven by a +3 dBm signal, the multiplier provides +15 dBm typical output power from 24 to 33 GHz. The Fo and 3Fo isolations are >20 dBc and >30 dBc respectively at 28 GHz. The HMC578LC3B is 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 -129 dBc/Hz at 100 kHz offset helps maintain good system noise performance. The RoHS packaged HMC578LC3B eliminates the need for wire bonding, and allows the use of surface mount manufacturing techniques.
