Information

Avago Technologies’ ADA-4743 is an economical, easy-touse, general purpose silicon bipolar RFIC gain block amplifi ers housed in a 4-lead SC-70 (SOT-343) surface mount plastic package which requires only half the board space of a SOT-143 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 amplifi cation. ADA-4743 is fabricated using Avago’s HP25 silicon bipolar process, which employs a double-diff used single polysilicon 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 multilayer interconnect to achieve superior performance, high uniformity, and proven reliability.
