Murata shrinks RF test connector footprint
At 1.0×1.0×0.55 mm, Murata’s SWL MM8330-2600 is one of the industry’s smallest RF/microwave coaxial connectors with an integrated mechanical switch. It reduces PCB mounting area by approximately 40% compared with the previous SWJ connector. When used with dedicated probes, the SWL reduces the total PCB footprint, including the keep-out area, by approximately 60% compared with the SWJ.
RF test connectors for wireless devices require not only mounting area for the connector itself but also sufficient clearance for probe access during circuit measurement. Murata’s design reduces both areas, providing greater flexibility in PCB component placement while maintaining low RF transmission loss and mechanical robustness.
The SWL connector operates from DC to 15 GHz with a nominal impedance of 50 Ω. Mounting the connector in an RF transmission line allows measurement of RF circuit and antenna characteristics. Its internal mechanical switch separates the RF and antenna circuits, allowing measurements without mutual interference when used with a dedicated Murata probe. Applications include output inspection of internal circuits in compact, high-density devices such as mobile phones, wearables, and smart watches.
The SWL MM8330-2600 is now in production. Dedicated probes are scheduled to enter mass production in December 2026.
