We are presently using AD8302 in our application for VSWR measurement.
I would like to use the same for our PA ALC application, where I would use it for RMS power measurement. Is it possible to use this using the Vmag pin.
Is yes, please tell me what I should do to the Vph pin (grounded or terminated to 50E...)
What is the input power range you are trying to measure? We have several low power log amps and RMS detectors found on this page:
I would recommend taking a look at the AD8312, AD8314, ADL5500, and the ADL5501.
Hope this helps,
