GaAs SP3T 2.7 V CDMA-GPS Switch DC - 2.5 GHz GND Pin 12 100 pF Balanced (symmetrical) RF Ports Low Cross Modulation Low Insertion Loss: 0.55 dB at 1 GHz High Isolation: 21 dB at 2 GHz Miniature Package: 3 mm 12-Lead PQFN 0.5 micron GaAs PHEMT Process ANT • • • • • • Functional Schematic GND Features MASWSS0060 V4 Pin 1 V1 The MASWSS0060 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability. Ordering Information RF3 100 pF 100 pF GND V2 GND 100 pF The design is symmetric and has been fully optimized for excellent cross modulation performance in all three paths while still maintaining excellent insertion loss and isolation. Note that since the design is symmetric, the user can assign CDMA cellular, CDMA PCS and GPS to ports RF1, RF2 or RF3 at his or her discretion. RF1 RF2 M/A-COM’s MASWSS0060 is an industry leading GaAs PHEMT MMIC single pole three throw (SP3T) CDMA-GPS switch in a low cost 3 mm 12-lead PQFN package. The MASWSS0060 is uniquely configured to enable switching from a common antenna port to CDMA cellular, CDMA PCS, or GPS ports.
