SMP RF Connectors for Compact, High-Frequency Applications

SMP connectors (GPO) are compact RF coaxial connectors designed for high-frequency signal transmission in applications where space efficiency and reliable electrical connections are important. Featuring a push-on coupling interface, SMP connectors support quick mating and compact interconnections in RF modules, microwave assemblies, and electronic equipment.

SMP Connector Types

Selecting the appropriate connector depends on the mating interface, mounting method, available space, and electrical design of the application.

Features of SMP Connectors

  • Interface Retention Styles
    Full detent, limited detent, smooth bore and catcher’s mitt.
  • 50 Ohm Impedance
    For 50-ohm RF and microwave systems.
  • Flexible Interconnections
    Cable-to-board and board-to-board applications.
  • Surface Mount Design
    Standard surface mount and swept-contact configurations.
  • Push-On & Blind Mate
    Quick mating and blind-mate installation.
  • Up to 40 GHz
    Subject to connector configuration and specifications.

Applications

Antenna & Radar Systems

SMP provide compact coaxial connections between antenna elements, RF front-end modules, and circuit boards.

Test & Measurement Equipment

In RF test fixtures, microwave measurement modules, and compact test assemblies, SMP push-on mating interface allows convenient connection and disconnection during testing and equipment setup.

Aerospace & Satellite Electronics

SMP can be integrated into compact avionics, satellite communication, and RF subsystem assemblies where space-efficient interconnections are required. Blind-mate configurations can support connections between aligned electronic modules.
