PCB RF Connector vs Cable RF Connector: Key Differences and How to Choose
Core answer: A PCB RF connector mounts directly onto a printed circuit board and transitions RF signals between the board and an external interface; a cable RF connector terminates the end of a coaxial cable and mates with a corresponding plug, jack, or board-side receptacle. They solve different mechanical problems and are often used together—not interchangeably—within the same signal chain. Who this is for: Engineers and procurement specialists evaluating interconnect options for wireless, test, or RF system designs at an intermediate technical level. If you are selecting connectors for a first prototype or comparing vendor offerings, the framework below applies directly. Who should read further first: Beginners unfamiliar with coaxial transmission line theory may benefit from reviewing impedance matching fundamentals (see IPC-2141 or any RF systems textbook) before applying the decision criteria here. What Each Type Actually Does PCB RF Connector A PCB RF connector—...
