KYOTO, JAPAN--(Business Wire / Korea Newswire)--Murata Manufacturing Co., Ltd. (TOKYO: 6981) (ISIN: JP3914400001) has begun mass production of the SWL series MM8330-2600RJ5 and MM8330-2600RK20, the world’s smallest RF / microwave coaxial connectors with a switch*. Measuring just 1.0 mm x 1.0 mm x 0.55 mm, the new connectors reduce PCB mounting area by approximately 40% compared with Murata’s previous SWJ series. When used with dedicated probes, the SWL series reduces its PCB footprint, including the keep-out area, by approximately 60% compared with Murata’s previous SWJ series.

As wireless devices incorporate more functionality, rising component counts are placing increasing pressure on limited PCB space. RF test connectors require not only mounting area for the connector itself, but also sufficient clearance around the component for probe access during circuit measurement.

Reducing the Space Required for RF Measurement

Murata addresses these constraints with a proprietary structure that combines its RF and mechanical design technologies. The design achieves miniaturization while maintaining low RF transmission loss and mechanical robustness. At 1.0 mm x 1.0 mm x 0.55 mm, the SWL series is smaller than Murata’s previous SWJ series, which measures 1.4 mm x 1.2 mm x 0.65 mm, allowing greater flexibility in PCB component placement.

When used with the dedicated automatic or manual probe, the connector requires less clearance around the test point, reducing the total board area required for RF measurement. The dedicated probes are scheduled to enter mass production in December 2026.

Supporting Frequencies up to 15 GHz

The SWL series supports a frequency range from DC to 15 GHz with a nominal impedance of 50 Ω. The MM8330-2600RJ5 is supplied on reels of 5,000 pieces, while the MM8330-2600RK20 is supplied on reels of 20,000 pieces.

Murata will continue developing smaller electronic components and solutions that enable more effective use of limited PCB space, supporting higher-performance and more compact smartphones and wearable devices.
