Secure Locking SMPS RF Connectors

Amphenol SV Microwave connectors ensure robust connectivity in high-vibration environments with their quarter-turn, bayonet-style coupling nut

Image of Amphenol SV Microwave Secure Locking SMPS RF ConnectorsThe Amphenol SV Microwave secure locking QuarterBack® product line features a bayonet-style coupling nut to prevent push-on connectors from coming loose in high-vibration and shock environments. In addition to this line, the secure-locking SMPS RF connectors bring four high-frequency solutions to the table: a cable assembly and cable connector for Ø.047" cable type as well as edge-launch and surface-mount PCB connectors.

These connectors feature a high-frequency SMPS interface and deliver reliable performance up to 65 GHz. Ideal for space-constrained, high-frequency applications, they enhance the versatility of the QB family.

Features
  • Quarter-turn bayonet locking feature on a standard SMPS interface
  • Low insertion/removal forces compared to standard full detent SMPS connectors, which means less torque on board-mount connector solder joints during mating and de-mating
  • Spring-loaded positive mating feature allows excellent electrical performance even in extreme vibration environments
  • DC to 65 GHz
Applications
  • Bench-top testing
  • High-vibration environments
  • Applications requiring a high number of mating cycles
