| These cable connectors are suitable for microwave applications and have been designed and built by Delta Electronics Manufacturing. These 2.92 mm connectors are aimed at a wide range of industries developing applications requiring frequency coverage up to 40 GHz, including defence, aerospace, high speed mobile and fixed line telecommunications systems and general test and instrumentation applications. |

A key feature of the SMK range is a maximum VSWR of 1.15:1 for cable connectors operating from DC to 18 GHz and 1.3:1 for models from 18 to 40 GHz. The maximum VSWR for receptacles and adapters is 1.15:1 from DC to 18 GHz and 1.25:1 from 18 to 40 GHz.
Interfacing is similar to that of SMA connectors, but these devices use an air dielectric and Noryl support bead to give a higher cut-off frequency and smaller size. The internal design is optimised using sophisticated electromagnetic finite element analysis models and simulation to provide a low reflection coefficient. A thick wall construction delivers electrical reliability and mechanical strength over SMA designs.
Additional technical characteristics include voltage ratings specified at 335 Vrms at sea level or 85 Vrms at 70,000 ft, while dielectric withstanding voltage for the cable connectors and receptacles is quoted at 1 kVrms at sea level and 1.5 kVrms at altitude. Nominal impedance is 50 Ω and insulation resistance is 5 GΩ minimum. RF leakage is specified at -100 dB at 2.5 GHz.
Field replaceable receptacles are available in three mounting flange configurations. They suit a number of hermetic seal and accessory pin dimensions. Operating temperature range is -55 to +135°C and vibration, shock, thermal shock, corrosion and moisture resistance characteristics meet MIL-STD-202 norms.
