ADA-4543

Overview
...y-touse, 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 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-4543 is fabricated using Avago’s HP25 silicon bipolar process, which employs a double-diffused 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 indu...
