AD8368 - AGC operation

Question asked by veera on Nov 9, 2012

Our application requires constant output power for wide range of input power ( +5 to -65 dBm). Can two AD8368 can be cascaded to achieve this?  Is there any special precaution to be taken during cascaded operation of two AD8368. We are planning to set the gain point on both AGC for the output power of 0 dBm, so that first AGC can convert +5 to -22 dBm signal to 0 dBm and second AGC can convert the original -23 to -44 dBm signal to the 0 dBm. The remaining range of -45 to -65 can be converted into -1 to -21 dBm.

Can this approach be implemented?
