Coaxial Switch Type DX Description RF Circuit: Actuator: Connector: Frequency: The Type DX Coaxial Switches are designed for high average power applications over a 0-6.5GHz frequency band. They use SC connectors with one inch center-to-center spacing. SPDT High Power Latching and Failsafe SC 0-6.5GHz These switches utilize HCI (heat conducting dielectric) to increase the average power handling capabilities. Test results on a large number of components employing HCI have consistently indicated a CW power rating 2.5 times greater than obtainable with conventional low-loss dielectric materials. These switches are available in latching or failsafe models, with or without indicating switches. The latching models use DowKey’s Type D switch magnetic latching actuator featuring a balanced rotating armature. The failsafe models use DowKey’s Type D switch failsafe actuator featuring dual holding power...a permanent magnet and electromagnet. This switch is part of a DowKey family of switches. Other types in this family are referenced below. Type D DO Conn. N &TNC SMA Schematic Freq. 1 2.4 GHz 1 8 GHz #1.
