Including K-type connectors, Ducommun Technologies’ QK Series coaxial multi-position switches exhibit frequencies from DC to 40 GHz. The SP3T-SP6T devices present a nominal RF impedance of 50 Ohm and an operating life of >1,000,000 cycles over an ambient operating temperature range from -35°C to 85°C. The MIL-E-5400- and Mil-S-3928-compliant units demonstrate a max. switching time of 15 ms in a break-before-make switching sequence. Actuator options include normally Open and TTL circuitry with integrated indicator circuits. Terminated models are available with a 2.4-mm connector.
