The HMC575LP4 & HMC575LP4E are x2 active broadband frequency multipliers utilizing GaAs PHEMT technology in a leadless RoHS compliant SMT package. When driven by a 3 dBm signal, the multiplier provides +17 dBm typical output power from 6 to 9 GHz. The Fo and 3Fo isolations are 15 dBc with respect to output signal level. This frequency multiplier features DC blocked I/O's, and 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 -140 dBc/Hz at 100 kHz offset helps maintain good system noise performance. The HMC575LP4 & HMC575LP4E are compatible with surface mount manufacturing techniques.
