SMP-MAX Connectors Radiall SMP-MAX Connectors address the most demanding wireless telecom applications required for the new generation of infrastructure compact equipment. A patented impedance matching insulator is optimized for a larger operating gap between connectors making it easier for engineers to handle a board-to-board distance tolerance of at least .078' (2.0mm) without a spring, which is 300% more than the standard SMP connector. The Radiall SMP-MAX connectors feature a 3° minimum tilt (radial travel), have an operating frequency range of DC to 6GHz, and a 1.2 maximum VSWR guaranteed at DC to 3GHz.
