The MMS006AA is a DC-to-20 GHz, non-reflective gallium arsenide (GaAs) pseudomorphic high electron-mobility transistor (pHEMT) single pole double throw (SPDT) monolithic microwave integrated circuit (MMIC) switch in a compact die size: 0.85 mm × 1.30 mm × 0.1. The switch delivers over 40 dB of isolation across the DC-to-20 GHz band while maintaining a low insertion loss of less than 2.0 dB. The switch is also available in a plastic leadless 3 mm x 3 mm smt package. The RF ports are internally matched to 50 Ω, which allows for easy integration into multi-chip modules (MCMs).
