V2 Application Schematic Description M/A-COM's MASW-008955 is a GaAs pHEMT MMIC single pole three throw (SP3T) switch in a lead-free 2 mm 8-lead PDFN package. The MASW008955 is ideally suited for applications where low control voltage, low insertion loss, high isolation, small size, and low cost are required. Typical applications are for filter and antenna switching in WLAN or Bluetooth systems that connect separate receive functions to a common antenna This part can be used in all systems operating up to 3.5 GHz requiring low control voltage. The MASW-008955 is fabricated using a 0.5 micron gate length GaAs pHEMT process. The process features full passivation for performance and reliability.

For use at low voltage, M/A-COM recommends connecting pin 2 to a voltage equal to the most positive control voltage. 12. Negative control voltage may be used. The `1' in the table would be the most positive (0 V) and the `0' would be the most negative (-3 V for example). 3 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions * North America Tel: 800.366.2266 / Fax: 978.366.2266 is considering for development.
