AD8367 oscillations



Hi,

We use an AD8367 for AGC control of an 140 MHz IF signal downconverted
by radio stages.

Problem is on one board (we have 4 independent boards). With multipath
on radio, this circuit oscillates. We don't know what is the HP high
pass filter with CHP and RHP.

They says that with RHP=100 ohms it attenuates the oscillations on the
figure 31.

Do you have same problem with this circuit ?

Best regards.
