Up To 6 Ghz Low Noise Silicon Bipolar Transistor - Agilent(hewlett-packard)

Hewlett-Packards AT-41410 is a general purpose NPN bipolar Transistor that offers excellent high frequency performance. The AT-41410 is housed in a hermetic, high reliability 100 mil ceramic package. The 4 micron emitter-to- emitter pitch enables this transis- tor to be used in many different functions. The 14 emitter finger 1 interdigitated geometry yields an intermediate sized Transistor with impedances that are easy to match for low noise and moderate power applications. This device is de- signed for use in low noise, wideband Amplifier mixer and Oscillator applications in the VHF, UHF, and Microwave frequencies. An optimum noise match near 50 at 1 GHz , makes this device easy to use as a Low Noise Amplifier The AT-41410 Bipolar Transistor is fabricated using Hewlett-Packards 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 ion- implantation, self-alignment techniques, and gold metalization in the fabrication of this device.
