Start with the operating envelope
RF cable selection should begin with the required frequency band, acceptable insertion loss, impedance, routing space and environmental conditions. A cable that is electrically suitable can still be the wrong choice if bend radius, repeated flexure or connector geometry is incompatible with the installation.
Compare the parameters that change the system
- Frequency capability: confirm the cable and both connector interfaces for the full operating band.
- Insertion loss: compare loss at the actual operating frequency and required length rather than a single headline value.
- Flexure and bend radius: separate static routing, repeated flexing and continuous-flex applications.
- Shielding: match shielding effectiveness to interference and emissions requirements.
- Power handling: consider frequency, temperature, altitude, VSWR and connector/interface limits.
- Phase stability: important for phased arrays, precision measurement and electrically matched paths.

An RFQ should include cable family or performance target, connector A, connector B, length, units, operating frequency, environment and any phase/length matching requirement.
