Hittite's new GaAs pHEMT MMIC SP4T switch module is designed for use in microwave radio, VSAT, military & space, fiber optic and broadband test applications from DC to 20 GHz. The HMC-C071 is a general purpose, broadband, non-reflective GaAs pHEMT SP4T switch which is rated for operation from DC to 20 GHz. This broadband operation combined with high isolation of better than 32 dB up to 20 GHz, and low insertion loss of 3.5 dB up to 20 GHz, makes the HMC-C071 appropriate for a wide range of applications spanning microwave radio, VSAT, radar, telecom and test instrumentation. The device also features very fast rise and fall time specifications of 17 ns. High P1dB and input IP3 performance of +24 dBm and +40 dBm respectively from 0.5 GHz to 20 GHz, also make the HMC-C071 well suited for applications requiring high linearity. A CMOS interface allows the HMC-C071 to operate with control voltages of 0 and +5V from a single +5V supply, while drawing only 1.4 mA.
