ADA-4643 - Hewlett-Packard

ADA-4643 Silicon Bipolar Darlington Amplifier

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 structure provides inherent broad bandwidth performance, resulting in useful operating .
