HMC992 is a VGA with integrated detector. Its nominal operationg frequency range is 50 to 1000 MHz. I want to use it in the region of 40- 50 MHz. What would be the effect on its performance as AGC ? I will be using it as an AGC. Has anybody tested it or used it below 50 MHz? kindly suggest me what should I do? Or suggest me any other VGA IC having integrated Detector that can be used in 40-50 MHz region. One such IC is AD8368 but its detector sensitivity is -30 dBm, and I need atleast -60 dBm detector sensitivity.
Waiting for your experienced feedback.
