Description
Avago’s AT-42000 is a general purpose NPN bipolar transistor chip that offers excellent high frequency performance. The 4 micron emitter-to-emitter pitch enables this transistor to be used in many different functions. The 20 emitter fnger interdigitated geometry yields a medium sized transistor with impedances that are easy to match for low noise and medium power applications.
