The NMS8K is an RF coaxial switch for DC to 40 GHz applications, with SP7T to SP8T configurations and 50 Ω impedance. It uses 2.92 mm female connectors and mounts via four 4.1 mm through-holes. Insertion loss ranges from 0.5 dB (DC-12 GHz) to 1.1 dB (26.5-40 GHz); isolation decreases from 70 dB to 50 dB. VSWR is specified up to 2.0. Operable with +12 V, +24 V, or +28 V, it draws 140-300 mA. Switching time is 15 ms max, with 2 million cycle life. Operating temperature is -25 °C to +65 °C, extendable to -45 °C to +85 °C. Mechanical dimensions are 41 × 41 × 53 mm. Switching sequence is break-before-make. Supports TTL control and mechanical indicators. Vibration tolerance is 10 G RMS (20-2000 Hz), with 30 G non-operating shock.
kTB Solutions supplies RF coaxial switches work at DC~67GHz, with lift cycle up to 2 million times. We provide standard high performance switches, as well as special options like Common Anode, low intermodulation.
