As reported at UK electronics design engineering site newelectronics, Murata has introduced a series of RF micro coaxial cable connectors which the company claims is "the thinnest in the world," with a profile of 1 mm maximum. The Murata JSC series is designed for RF signal transmission in mobile phones, smartphones, PDAs and wireless mobile terminals. The JSC cable connector has been developed as the result of requirements from the industry for lower profile connectors.

The receptacle measures 2 x 1.8 x 0.5 mm and the mated height of both the receptacle and cable plug is 1.0 mm maximum. According to Murata, the part can withstand up to 30 mating cycles and emits an audible click on mating. Voltage standing wave ratio (VSWR) is 1.3 maximum up to 3GHz, 1.4 maximum between 3 and 6GHz, 1.5 maximum between 6 and 9GHz, and 1.6 maximum between 9 and 12GHz.
The low profile of the connector has been achieved by introducing a C shaped spring terminal on both the outer and inner conductors, says Murata. Suitable for cable diameters over 0.81 mm, the connector's inside structure is optimized to ensure RF performance up to 12 GHz, while the connector itself comprises a receptacle and a cable plug.
