Miniature DC-26.5 GHz SPDT Switch
The CR-53 Switch is a broadband, SPDT, electromechanical, coaxial switch designed to
switch a microwave signal from a common input to either of two outputs. The CR-53 Series
has a higher operting Temperature range than the commercial CCR-53 and higher frequency
range than the Elite CR-33 series. The characteristic impedance is 50 Ohms. The switches
are small with connector spacing compatible with SMA connectors.
The CR-53 series switch is offered with either a failsafe or latching actuator. This design is
compatible with the two most common mounting hole patterns. The CR-53 series switch is
interchangeable with a variety of switches.
