2.92 mm Connectors, Adapters, and Cable Assemblies

Amphenol RF high-frequency 50 Ω threaded connectors deliver precision and durability up to 40 GHz

Image of Amphenol RF 2.92 mm Connectors, Adapters, and Cable Assemblies Amphenol RF 2.92 mm connector series, commonly known as K connectors, offer precision-engineered performance tailored for satellite communications, lab instrumentation, and test environments. With an air dielectric and compact design, these connectors maintain exceptional RF characteristics while supporting seamless mating with SMA, 3.5 mm, and other K-type interfaces. Their rugged construction ensures reliable operation in demanding settings.

Built to the MIL-STD-348 interface standard, 2.92 mm connectors feature low VSWR, excellent return and insertion loss, and high power-handling capability, extending usable bandwidth up to 40 GHz. A shorter pin ensures that the outer bodies engage before the contacts, reducing wear and extending connector lifespan. These features make them ideal for high-frequency, high-reliability applications

Features
  • High-frequency capability: Operates up to 40 GHz with low VSWR and excellent return/insertion loss
  • Interoperable design: Threaded interface compatible with SMA, 3.5 mm, and other K-type connectors
  • Rugged and durable: Threaded coupling and machined bodies designed for frequent mating cycles
  • Power-capable and reliable: Handles high RF power in laboratory or field deployments
  • MIL-standard compliance: Meets MIL-STD-348 dimensional standards for consistent performance
Applications
  • Laboratory and bench testing: Suitable for VNAs, spectrum analyzers, and calibration equipment
  • SATCOM infrastructure: Ideal for terrestrial satellite and ground station RF interfaces
  • Quantum computing and microwave research: Reliable for advanced high-frequency experimental setups
  • Optical and millimeter-wave instrumentation: Ensures signal purity and repeatability in precision measurements
  • High-end aerospace and defense systems: Rugged enough for demanding operational environments
