MASWSS0040 GaAs DPDT Diversity Switch 0.5 - 3.0 GHz Features • • • • Rev. V5 Functional Schematic Low Insertion Loss 0.7 dB at 2.4 GHz Low Cost 3 mm 12-Lead PQFN Package Ideal for WLAN IEEE 802.11b 0.5 micron GaAs PHEMT Process Description M/A-COM’s MASWSS0040 is a GaAs pHEMT MMIC DPDT diversity switch in a low cost miniature 3 mm 12-lead PQFN package. The MASWSS0040 is ideally suited for applications where very small size and low cost are required. Typical applications are for WLAN IEEE 802.11b/g systems that employ two antennas for transmit and receive diversity. This part is designed for low insertion loss and allows for independent control and selection of each switch path. This part can be used in all systems operating up to 3.0 GHz requiring moderate power and diversity switching. The MASWSS0040 is fabricated using a 0.5 micron gate length GaAs pHEMT process. The process features full passivation for performance and reliability.
