DESCRIPTION
Avago Technologies’ 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 fT at 6V BVCEO). The process utilizes industry standard device oxide isolation technologies and submicron aluminum multi-layer inter-connects to achieve superior performance, high uniformity, and proven reliability.
