The AT-31625 can be used as a driver device or an output device, depending on the specific application. The AT-31625 features +28 dbm CW output power when operated at 4.8 volts. Excellent gain and superior efficiency make the AT-31625 ideal for use in battery powered systems. Applications Medium Power Driver Device for Cellular/PCS, ISM 9, WLAN Output Power Device for ISM 9, Cordless, WLAN EMITTER 1 2 BASE 3 EMITTER The AT-31625 is fabricated with Hewlett Packard s 1 GHz F t Self- Aligned-Transistor (SAT) process. The die are nitride passivated for surface protection. Excellent device uniformity, performance and reliability are produced by the use of ion-implantation, selfalignment techniques, and gold metalization in the fabrication of these devices. 4-43 5965-5911E
