MACOM’s MASW-008566 is a GaAs pHEMT MMIC single pole four throw (SP4T) high power switch in a low cost 4 mm 16-lead PQFN package. The MASW-008566 is ideally suited for applications where high power, low control voltage, low insertion loss, high isolation, small size, and low cost are required. Typical applications are for GSM and DCS handset systems that connect separate transmit and receive functions to a common antenna, as well as other handset and related applications. This part can be used in all systems operating up to 3.0 GHz requiring high power at low control voltage. The MASW-008566 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability.
