Expanding its reach into the broadcast and cable TV markets, Teledyne Relays has introduced the Series CCR-33M coaxial switch, a single-pole, double-throw device designed for optimum performance in 75 Ω applications. The CCR-33M can be used in broadcast and cable TV systems, cable modem networks, and aircraft and home video entertainment systems, according to the company.

The electromechanical device switches signals from a common input to either of two outputs, operating from DC to 3 GHz with characteristic impedance of 75 Ω. It is offered with either a failsafe or latching actuator at voltages of 28, 15 or 12 V d.c. It has a 20 ms switching time and features indicator circuits, TTL and self-cutoff options.

Weighing 46,78 g, the CCR-33M is offered in a standard SPDT RF switch package or in Teledyne's narrow-body configuration and features female mini-SMB connectors. Its design is also compatible with the two most common mounting hole patterns. A narrow-width body is available as an option. The CCR-33M meets MIL-STD-202 requirements for shock and vibration. It has a warranty of two years or 1 million cycles and features an MTBF of 7,3 million hours.
