Description
Hewlett Packard's AT-38086 is a low cost, NPN silicon bipolar junction transistor housed in a surface mount plastic package. This device is designed for use as a pre-driver or driver device in applications for cellular and wireless communications markets. At 4.8 volts, the AT-38086 features +28 dBm pulsed output power, Class AB operation, and +23.5 dBm CW. Superior efficiency and gain makes the AT-38086 an excellent choice for battery powered systems. The AT-38086 is fabricated with Hewlett Packard's 10 GHz Ft SelfAligned-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.
