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 MASWSS0175 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability. Ordering Information Part Number Package MASWSS0175 Bulk Packaging MASWSS0175TR-3000 3000 Piece Reel MASWSS0175SMB Sample Test Board Note: Reference Application Note M513 for reel size information. N/C N/C M/A-COM’s MASWSS0175 is a GaAs PHEMT MMIC DPDT diversity switch in a lead-free 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.
