Cables for wireless: 2.92-mm assemblies support 5G, mil/aero, instrumentation applications

Amphenol RF offers preconfigured 2.92-mm cable assemblies designed on flexible 0.85-inch conformable cable. “This assembly is available in the straight plug (male) to straight plug (male) configuration in various standard lengths from 6 inches to 1 meter,” Amphenol RF said. “The durable 2.92-mm assembly provides an excellent solution for demanding applications requiring high-frequency transmission while providing high mechanical stability and excellent repeatability. It is well-suited for use in a variety of industries including military and aerospace, 5G wireless, and instrumentation.”

The company added that the assemblies allow “for a tight bend radius while providing low VSWR [Voltage Standing Wave Ratio] and excellent return and insertion loss. In addition, this assembly offers excellent power handling capability, which makes it an ideal solution for communication receivers and transmitters, satellite communication equipment, laboratory testing, and microwave applications.”

The assemblies’ RF interconnect is similar to the SMA, with a smaller internal body diameter and air dielectric to support a frequency range up to 40 GHz. The connectors, which are gold-plated stainless steel, are intermateable with SMA and 3.5-mm connectors. “The male pin is shorter than that of an SMA or 3.5-mm to ensure that the outer contacts of the male and female connectors engage before the pin and female receptacle do,” Amphenol RF explained. “This ensures that the pin and socket will not see excessive wear and mating stress by misalignment with an SMA or 3.5-mm.”
