1. A co-axial infrared filter comprising:
a body having
a wall forming an outer conductor characterized by a filling hole, and
a cylindrical central cavity having an open first end and an open second end; and
a first Subminiature version A (SMA) connector mechanically coupled to the open first end of the body and a second SMA connector mechanically coupled to the open second end of the body, wherein a respective connector pin of each of the first SMA connector and the second SMA connector are positioned along a long axis of the body and electrically coupled proximate the filling hole to define an inner conductor.
