AD8309 to Control ADL5530 RF Gain Stage

Good morning-

I'm planning to use an AD8309 as an IF limiter for an all-analog FM receiver design. While I realize that FM doesn't typically call for any type of AGC, I would like to use the VLOG/RSSI output to control the gain of an ADL5530 in the RF section of the receiver. Given the speed of the AD8309 and the relatively large control loop, can I expect significant stability issues when used in this manner? Are there any Analog/Linear application notes available to help with designing a proper compensation network?

Thanks in advance,

-EHaag
