Overview
ADA-4789 Silicon Bipolar Darlington Amplifier Data Sheet Description Avago Technologies’ ADA-4789 is an economical, easyto-use, general purpose silicon bipolar RFIC gain block amplifiers housed in SOT-89 surface mount plastic package.
The Darlington feedback structure provides inherent broad bandwidth performance, resulting in useful operating frequency up to 2.
5 GHz.
This is an ideal device for small-signal gain cascades or IF amplification.
ADA-4789 is fabricated using Avago’s HP25 silicon bipolar process, which employs a double-diffused single poly-silicon process with self-aligned submicron emitter geometry.
The process is capable of simultaneous high fT and high NPN breakdown (25 GHz f...
