  How about this circuit?  This is the one that I made, that
had introduced by Japanese CQ Ham magazine few years ago -
designed by JA1DWO. I used this to check my Drake 2880 converter
modification. It works well with input 50.01MHz 200mW.

  Sorry that chart is written in Japanese. L is lead line with
12mm length. 1S1588 is most popular Si SW-Di for all-purpose.
May be any type of Si-Di will bw able to replace it.

  I also have a web page about S-band downconverter. Here is
the URL. But sorry it all written in Japanese only.
