Southwest Microwave’s SSBP-20 miniature microwave coax contact assemblies fit into the small, standard size 20 contact cavities of D-subminiature connectors and also size 20 (and larger) contact cavities for standard MIL-DTL-38999 circular connectors. They can be used interchangeably with non-coax signal contact assemblies. Applications range from airborne to test, and from missile and space to mobile communications. Benefits include miniaturization, increased reliability, and reduced system costs. They are resistant to vibration (tested to 2000 Hz, random and sine, at 150°C) and shock (tested three-axis, 100 g). The interface is 0.9 mm, which permits economical use at both RF and extreme millimeter wave applications.
