Description
The MASW-007107 is a broadband GaAs pHEMT MMIC SPDT switch in a lead-free 2 mm 8-lead PDFN package. Typical applications are for WLAN IEEE 802.11a + b/g, and MIMO. Other applications include test equipment requiring ultra fast switching speeds. Designed for low insertion loss, this SPDT switch maintains low loss up to 8.0 GHz.
The MASW-007107 is fabricated using a 0.5 micron gate length GaAs pHEMT process. The process features full passivation for performance and reliability.
