.. Agilent ADA-4543 Silicon Bipolar Darlington Amplifier Data Sheet Features - Small Signal gain amplifier - Operating frequency DC - 2.5 GHz Description Agilent Technologies’ ADA-4543 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 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 Agilent’s HP25 silicon bipolar...
