[Premium-Rx] AM Synchronous Detector Article on Our Webpage

[Ahmet Gundes]

Hi Jan,

Correct me if I am wrong but it appears the S041P is used
only as a "Limiter" in this circuit.  This can easily be 
replaced by some alternatives. Couple of them come to my
mind such as:

TA7061BP Limiter which is used in the ECSS module of NRD535
this part is obsolete but can be found in the market for about
$ 2.00

A popular part, Philips SA604AD, has a good limiter. It can also 
be used but has a lot more in it than just a limiter. And it is available in the market only in SMD package ( about $ 7.00 ).

Regards
Ahmet
