Re: Unidentified Connector

Fascinating to dig around.

The connector was developed in the 1980's and originally designated as the OSP™ connector by M/A-Com (Microwave Associates).
The other connector was the OSM which became the SMA (SubMiniature version A).  The OSP became the BMA a military standard MIL-STD-348B and is otherwise known as the Blind-Mate A.
The OSM was one of the Omni-Specta brand when I first came across it in the late 60s. So presumably the OSP was originally designated Omni Spectra push.

In June 2003, XMA Corporation, located in Manchester, New Hampshire, purchased from MACOM the Omni Spectra line of coaxial attenuators and terminations

Thanks Rob


That’s a match.  It’s an OSP – spec to 22 GHz.
