ADA-4543 - AVAGO

ADA-4543 Silicon Bipolar Darlington Amplifier

Avago Technologies’ ADA-4543 is an economical, easy-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 fre.
