MASWSS0039 GaAs DPDT Diversity Switch 4.5 - 6.0 GHz Features The MASWSS0039 is ideally suited for applications where very small size and low cost are required. Typical applications are for WLAN IEEE 802.11a systems that employ two antennas for transmit and receive diversity. This part can be used in all systems operating between 4.5 GHz and 6.0 GHz requiring moderate power and diversity switching. The MASWSS0039 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability. Ordering Information1 N/C N/C Ctrl 1 Ctrl 2 Port 3 Port 4 Ctrl 4 Ctrl 3 N/C M/A-COM’s MASWSS0039 is a GaAs PHEMT MMIC DPDT diversity switch in a low cost 3 mm 12lead PQFN package. It is designed for low insertion loss and allows for independent control and selection of each switch path. It integrates blocking capacitors on all RF ports and thus eliminates the need for additional off-chip DC blocking capacitors.
