Stable, Closed-Loop Automatic Power Control for RF Applications
Stable, Closed-Loop Automatic Power Control for RF Applications. The circuit described in this document provides closed-loop, automatic power control using a VGA (ADL5330) and a log detector (AD8318). Due to the high temperature stability of the AD8318, this circuit provides stability over temperature because the AD8318 RF detector ensures the same level of temperature stability at the output of the ADL5330 VGA
