RF switch connector reduces overhead for test provision

Murata’s SWF series of switched coaxial connectors reduce the footprint and mounting height of test points for microwave circuits.

The new connectors, MM8130-2600, measure 2.5mm x 2.5mm x 1.5mm and allow reliable attachment of test probes during development as well as production testing. In addition to offering a valuable saving compared to the previousgeneration SWD series, the SWF series retains compatibility with existing test probes and therefore requires no changes to test-equipment setup.

Other key features of this coaxial switched connector include its wide operating frequency range from DC to 6GHz, which covers all popular frequency bands. Insertion loss is 0.1dB maximum in the DC to 3GHz range and 0.2dB maximum in the 3 to 6GHz range, minimising the effect on the circuit’s performance. Isolation is 20dB minimum in the DC to 3GHz range and 15dB in the 3GHz to 6GHz range. In addition, the Voltage Standing Wave Ratio (VSWR) of 1.2:1 in the DC to 3GHz range, and 1.3:1 in the 3GHz to 6GHz range, transfers signal power efficiently to the test equipment. The connectors also have high mating durability of 100 cycles.
