The usual way people do that is to use a Ku-band LNBF -- the same type
that people use for satellite TV.
  These downconvert into L-band, so a DBSRX or WBX card can be used to
receive the downconverted
  signal.  Get one that is "digital ready"--they have better local
oscillators that are more stable.

Typical units downconvert 11.7GHz to 12.7GHz down to 950Mhz to 1800MHz.
