RF Connector Guide: Types, Selection Criteria, and Applications
Core answer: An RF connector is a precision electromechanical interface that transfers radio-frequency signals between cables, PCBs, and antennas with controlled impedance and minimal signal loss. Choosing the wrong type—or the right type but with mismatched impedance—causes reflections, insertion loss, and system-level failures that are difficult to trace after assembly. Who this guide is for: Electronics engineers, RF system designers, and technical procurement teams who need to specify, evaluate, or compare RF connectors for a project. If you are entirely new to RF concepts, you may want to review basic transmission-line theory first; if you are already specifying connectors daily, this guide offers a consolidated decision framework and a checklist of the most common specification errors. Who this guide is not for: Individuals looking solely for consumer-grade installation guidance; the connector families covered here are oriented toward RF/...
