   Have you tried a synchronous detector? Generate a well-limited square   
   wave at the IF frequency and use it to switch a full wave diode   
   bridge. This will recover - with perfect linearity - any AM signal,   
   even one modulated well beyond 100% (provided it has been carried out   
   properly).
