SSB High Density Interconnect Solutions

A Family of Connectors for Microwave and Digital Applications


Interface (size 20)

This is a microscopic picture showing both sides of the SSBP (size 20) interface. On the left is the pin end and on the right is the socket end. The interface is 0.9 mm in diameter and the dielectric at the interface is air.

SSB Interface

The SSB family of connectors (SSBP, SSBT, and SSBB) is designed around a common airline concept. The SSB interface has air dielectric and the center conductor is captured with high temperature plastic bead, the SSB utilizes the same materials and construction that Southwest Microwave has used for years in other air dielectric connectors.

Excellent microwave performance is obtained by utilizing transmission line principles throughout the entire interconnect system. This includes compensated transitions, high quality plating, and other proprietary innovations.

The use of air as the dielectric instead of PTFE gives the SSB advantages in performance over temperature and other environmental conditions. It creates a lower loss transmission path. And it allows for greater phase stability in mechanically strenuous environments (e.g. misalignments, vibration, temperature, etc.).

  • Air dielectric
  • High frequency (67 GHz)
  • Bead capture
  • Low VSWR
  • High density
  • Low loss

 

SSBP

This is the push-on contact version of the SSB family. The SSBP is designed to be used in industry standard multi-contact connectors or can be arrayed in a custom envelope for maximum flexibility. The SSBP interface engagement starts with a low insertion force mate, then the spring loaded sleeve is compressed when the multi-contact connector is fully engaged.

The SSBP interface sides are designated as pin and socket following the convention of the multi-contact connector industry. Standard insertion and retraction tools will work with SSBP contacts.

  • Pin/socket pairs
  • Terminated for cable or end launch
  • Multiple contact sizes available:
    20, 16, 12 and 8
  • Versions for 38999, D-sub,
    Micro-D, etc.
  • Works with standard insertion / extraction tools

SSBT

This is the threaded version of the SSB family. The SSBT is designed to be used as a replacement to traditional microwave connectors where there are smaller size or higher frequency requirements. The SSBT is available in field replaceable, cabled or adapter configurations.

SSBB

This is the bulleted version of the SSB family. The SSBB is designed to be used in board-to-board or module-to-module stacking applications. The bullet allows for misalignment of connectors while maintaining a good microwave interconnect. The SSBB has a bullet diameter of .065" and is available in different lengths. The smallest length is .110" and it allows a .012" axial misalignment. Longer bullets would allow more misalignment.

SSBB design and materials can be compatible with commercial SMT processing per IPC/JEDECJ-STD-020.1 (March 2008), with Tp = 260ºC and tp = 20 sec., when specified.

  • Air dielectric minimizes interface discontinuities
  • Board-to-board
  • Module-to-module
  • Less than .100" centers
