ADA-4643-TR2RF/IF射频/中频RFID的射频放大器规格书PDF中文资料

描述 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 structure 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.
