The HMC578 die is a x2 active broadband frequency multiplier utilizing GaAs PHEMT technology. When driven by a +3 dBm signal, the multiplier provides +17 dBm typical output power from 24 to 33 GHz. The Fo and 3Fo isolations are >25 dBc and >36 dBc respectively at 28 GHz. The HMC578 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.
