approximately 40% compared to Murata's previous SWJ series. When used with the specific probes, the SWL series reduces the total PCB footprint, including the keep-out area, by approximately 60% compared to Murata's previous SWJ series.
As wireless devices incorporate more features, the increasing number of components puts increasing pressure on the limited space available on printed circuit boards. RF test connectors not only require a mounting surface for the connector itself, but also sufficient clearance around the component to allow probe access during circuit measurements.
Murata addresses these limitations with a proprietary structure that combines its RF and mechanical design technologies. This design enables miniaturization while maintaining low RF transmission losses and high mechanical robustness. Measuring 1.0 × 1.0 × 0.55 mm, the SWL series is smaller than Murata's previous SWJ series, which measures 1.4 × 1.2 × 0.65 mm, offering greater flexibility in component placement on the PCB.
When used with the dedicated automatic or manual probe, the connector requires less clearance around the test point, thus reducing the overall board area needed for RF measurements.
The SWL series supports a frequency range from direct current (DC) up to 15 GHz, with a nominal impedance of 50 Ω. The MM8330-2600RJ5 model is supplied in reels of 5,000 units, while the MM8330-2600RK20 model is supplied in reels of 20,000 units.
