The AT-42086 is housed in a low cost surface mount .085" diameter Note: 1. Refer to PACKAGING section "Tapeand-Reel Packaging for Semiconductor Devices." plastic package. The 4 micron emitter-to-emitter pitch enables this transistor to be used in many different functions. The 20 emitter finger interdigitated geometry yields a medium sized transistor with impedances that are easy to match for low noise and medium power applications. Applications include use in wireless systems as an LNA, gain stage, buffer, oscillator, and mixer. An optimum noise match near 50 up to 1 GHz, makes this device easy to use as a low noise amplifier. 86 Plastic Package Pin Connections EMITTER 4 420 Features BASE 1 The AT-42086 bipolar transistor is fabricated using Agilent's 10 GHz fT Self-Aligned-Transistor (SAT) process. The die is nitride passivated for surface protection. Excellent device uniformity, performance and reliability are produced by the use of ionimplantation, self-alignment techniques, and gold metalization in the fabrication of this device.
