M/A-COM's MASWSS0107 is a broadband GaAs PHEMT MMIC diversity switch in a low cost, lead-free 3 mm 12-lead PQFN package. The MASWSS0107 is ideally suited for applications where very small size and low cost are required. Typical applications are for WLAN IEEE 802.11a and 802.11b/g systems that employ two antennas for transmit and receive diversity. Other applications include cordless phones and base stations.Designed for high power, this DPDT switch maintains high linearity up to 6.0 GHz. The MASWSS0107 can be controlled with either two or four control signals. With four control signals each of the four insertion paths can be controlled individually. To control the switch with only two signals, tie pairs of control lines together. The MASWSS0107 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability.
