I note that the internal AGC/RSSI output functions (pin 12) of the AD607 have been deprecated on the later revisions of the data sheet.
I have the old 1995 copy as well as the latest version of the datasheet.
Does the device still support the internal AGC detector?
I assume there were issues with the performance or else it would not have been deleted.
If the AGC detector is still functional, I am very seriously considering specifying this device for our new air band transceiver second mixer, IF strip and AM detector.
Do you have any archived old application notes for the AD607?
Is the AD61009 a direct replacement for the AD607?
