MASWSS0175 GaAs DPDT Diversity Switch 4.5 - 6.0 GHz Rev. V1 Features N/C Port 1 Low Insertion Loss: 0.8 dB at 5.2 GHz Ideal for WLAN IEEE 802.11a 0.5 micron GaAs PHEMT Process Integrated DC Blocking Capacitors Lead-Free 3 mm 12-Lead PQFN Package 100% Matte Tin Plating over Copper Halogen-Free Green Mold Compound 260C Reflow Compatible RoHS* Compliant Version of MASWSS0039 N/C Functional Schematic PIN 1 Ctrl 1 Ctrl 2 Port 3 Port 4 Ctrl 4 Ctrl 3 The MASWSS0175 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 MASWSS0175 is fabricated using a 0.5 micron gate length GaAs pHEMT process. The process features full passivation for performance and reliability. Ordering Information 1 N/C N/C The MASWSS0175 is a GaAs pHEMT MMIC DPDT diversity switch in a lead-free 3 mm 12-lead 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.
