Can I use 50 ohm connectors in a 75 ohm system?

While a 50 ohm connector may physically mate with a 75 ohm connector, it is not recommended to mix impedances. Doing so creates an impedance mismatch that can increase reflections, raise VSWR and reduce signal integrity. The impact of this mismatch is more pronounced at higher frequencies and over longer cable runs.

For best results, engineers should always match the connector impedance to the system impedance. Amphenol RF offers both 50 ohm and 75 ohm versions of many popular connector families such as BNC, N-Type and SMB, making it easy to find the correct solution for your design.
