Following the discussion tonight after SARA Drakes, is this possibly the lowest insertion loss switch module board available on ebay?

Andy you could also look for this other switch board.

One could quibble over 0.1db differences but the specs for the 7992 switch IC quotes 0.6 db insertion loss @ 2GHz although it only is rated to 6GHz.

The PE42540 specs quote a min: insertion loss of 0.7db but only quote 0.8db insertion loss @ 3GHz.
