MASW-009460
GaAs DPDT Diversity Switch 0.5 - 3.0 GHz
Features
Low Insertion Loss 0.7 dB at 2.4 GHz Ideal for WLAN IEEE 802.11b 0.5 micron GaAs pHEMT Process Lead-Free 3 mm 12-Lead PQFN Package Halogen-Free ―Green‖ Mold Compound 260°C Reflow Compatible RoHS* Compliant version of MASWSS0040
Description
M/A-COM’s MASW-009460 is a GaAs pHEMT MMIC DPDT diversity switch in a lead-free 3 mm 12lead PQFN package. The MASW-009460 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 MASW-009460 is fabricated using a 0.5 micron gate length GaAs pHEMT process. The process features full passivation for performance and reliability.
