In summary, the SWD and SWF switch connectors are among the smallest RF test connectors available today. Their overall useful frequency range extends from DC to 6 GHz, with a maximum insertion Loss of only 0.2 dB. With any electro-mechanical interconnect system, the number of mating cycles, as well as the ability for the receptacle itself to remain attached to the PC board is of major importance.  The SWD and SWF products provide these quality features. Perhaps the biggest advantage is the backwards compatibility of the SWF and SWD switch connectors to the mating test probes which are used with these devices. All Murata’s manual and automated test probes can be used with either the SWD or SWF series of receptacles.
