Amphenol APC-7-3.5MM RF Coaxial Connector Adapter

Amphenol RF's 131-91046 APC-7mm Plug to APC-3.5mm Jack Adapter is a precision RF coaxial connector that bridges an APC-7 test port to an APC-3.5mm interface without introducing extra components in the signal path. It combines a male APC-7 plug on one end with a female APC-3.5 jack on the other in a straight configuration, delivering a 50-ohm impedance through the transition and providing a direct, low-loss connection for measurement chains. Used in laboratory test setups, this adapter enables interoperability between legacy APC-7 equipment and modern 3.5 mm test ports, reducing layout changes and simplifying instrumentation bridges in RF and microwave research. Part number 131-91046, manufactured by Amphenol RF, is designed for reliable, repeatable connections in 50-ohm systems, supporting bench-top characterization, calibration rigs, and development work that require quick interchange between these two common connector geometries.
