The SMP RF connectors have a subminiature interface which is similar to MMCX connectors but offers a frequency range of DC to 40 GHz. SMP subminiature connectors are commonly used in miniaturized high-frequency coaxial modules and are well-proven, offering a high level of flexibility in alignment tolerances. It is offered in both push-on and snap-on mating styles, available in a cable-to-board mated pair, the plug side can be provided in either right angle or straight with termination capability to either 0.047” or 0.086”, semi-rigid or conformable coax. JawDropper SMP connectors are suitable for a wide range of board-to-board and cable-to-board applications up to 40 GHz.
