The HMC576 die is a x2 active broadband frequ-ency multiplier utilizing GaAs PHEMT technology. When driven by a +3 dBm signal, the multiplier provides +17 dBm typical output power from 18 to 29 GHz. The Fo and 3Fo isolations are >20 dBc and >30 dBc respectively at 24 GHz. The HMC576 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 -132 dBc/Hz at 100 kHz offset helps maintain good system noise performance.
