We have chosen two VGAs AD8368 and AD8367 for Tx and Rx respectly.
I would like to know if I could use the internal detectors alone in this VGAs because I don't need a standalone AGC of these components. I prefer using these detetors to provide power measurement and then apply gain control by FPGA. Is it OK for this application ?
Thanks in advances,
The RSSI function won’t work in open loop mode – you must close the loop and feedback the DETO to the GAIN pin, along with sampling the output with the DETI pin.
