Toshiba announces smallest GaAs MESFET switch for Bluetooth, WLAN apps

Posted: 11 Nov 2004 ?? ?Print Version ?Bookmark and Share

Toshiba America Electronic Components Inc. (TAEC) and its parent Toshiba Corp. announced the release of TG2217CTB, a small, low-profile GaAs Metal-Semiconductor Field Effect Transistor (MESFET) single-pole dual-throw (SPDT) switch that is well-suited for use in multi-band/mode cellular antenna switch modules (ASMs), Bluetooth modules and WLAN applications.

The TG2217CTB SPDT switch is offered in a 1-by-1-by-0.38mm leadless 6-pin CSP package. It operates from DC to 3GHz requiring two control positive voltages also acting as bias supply. The control voltages are very low and 2.4V switching operation is possible.

This GaAs MESFET monolithic microwave integrated circuit (MMIC) features 0.35dB insertion loss at 1GHz (0.40dB at 2GHz) and 24dB isolation at 1GHz and 2GHz. Power handling performance is 17dBm P1dB at 2.5GHz.

Samples of the TG2217CTB will be available in Dec., priced at 20 cents each. Volume production is scheduled to begin in 1Q of 2005, at which time production pricing will become available.
