1 / 10 page Agilent ADA-4643 Silicon Bipolar Darlington Amplifier Data Sheet Description Agilent Technologies’ ADA-4643 is an economical, easy-to-use, general purpose silicon bipolar RFIC gain block amplifiers 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 struc- ture provides inherent broad bandwidth performance, result- ing in useful operating frequency up to 2.5 GHz. This is an ideal device for small-signal gain cascades or IF amplification. ADA-4643 is fabricated using Agilent’s HP25 silicon bipolar process, which employs a double- diffused single polysilicon process with self-aligned submicron emitter geometry. The process is capable of simulta- neous 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.
