Request about s2p file for AD8367

Dear Sir,

We are working on AD8367 chip as AGC. We would like to match to a custom frequency
not enlisted in the table of the DS. Hence request you to kindly send over the s2p file for
input and output ports if available at the earliest please. The board is getting into production.

Additionally some spurious out of the band oscillations are occurring at certain signal levels
over a window of 2 to 3 dB within the dynamic range. Before and after this oscillation point,
there is a sudden pedestal change in the noise floor. We removed the clamping transistor
at the gain pin and found no difference. Kindly let us know what may be the problem, and
possible guidelines to get a cleaner output, perhaps with a proven application circuit. Also,
we found that the max gain was only 32 dB as against 42.

Awaiting for your reply soon.

Thanking you,
