AT-42085

85 Plastic Package

Description

Hewlett-Packard’s AT-42085 is a

general purpose NPN bipolar

transistor that offers excellent

high frequency performance. The

AT-42085 is housed in a low cost

.085" diameter plastic package.

The 4 micron emitter-to-emitter

pitch enables this transistor to be

used in many different functions.

The 20 emitter finger interdigi-

tated geometry yields a medium

sized transistor with impedances

that are easy to match for low

noise and medium power applica-

tions. Applications include use in

wireless systems as an LNA, gain

stage, buffer, oscillator, and

mixer. An optimum noise match

near 50

Ω up to 1 GHz, makes this

device easy to use as a low noise

amplifier.

The AT-42085 bipolar transistor is

fabricated using Hewlett-Packard’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 ion-

implantation, self-alignment

techniques, and gold metalization

in the fabrication of this device.
