Microchip Technology, Inc. Wideband SP4T Switch low insertion loss SWITCH-SP4T

Our portfolio of MMIC switches targets a broad range of applications including those in electronic warfare, radars, instrumentation (test and measurement) and microwave communications. The portfolio comprises switches spanning DC to 20 GHz based on high-performance process technologies. The MMS008AA is a DC-to-8 GHz, non-reflective gallium arsenide (GaAs) pseudomorphic highelectron mobility transistor (pHEMT) single pole 4 throw (SP4T) monolithic microwave integrated circuit (MMIC) switch die. The switch delivers over 45 dB of isolation across the DC-to-8 GHz band while maintaining a low insertion loss of 1.6 dB. The RF ports are internally matched to 50 Ω, which allows for easy integration into multi-chip modules (MCMs). The MMS008PP3 device is the packaged version of the MMS008AA; a DC-to-8 GHz, non-reflective GaAs pHEMT single-pole 4 throw (SP4T) MMIC switch in a plastic leadless 3 mm × 3 mm SMT QFN package. The packaged switch delivers an average of 40 dB of isolation across the DC-to-8 GHz band while maintaining a low insertion loss of 1.8 dB. This switch includes an on-board binary 2:4 decoder circuit which reduces the required logic control lines. The control voltages are 0/–5 V, with a fixed bias of –5 V.
