Dow-Key® Microwave Releases SP6T High Performance Switch to the Reliant Switch™ Product Series

Dow-Key Microwave now offers a complete solution for Automated Test Equipment (ATE) applications with the recent release of the Reliant R461, a 1×6 bidirectional coaxial switch from the Reliant Switch™ product series.

Dow-Key Microwave now offers a complete solution for Automated Test Equipment (ATE) applications with the recent release of the Reliant R461, a 1×6 bidirectional coaxial switch from the Reliant Switch™ product series.

The Reliant Switch™ product series encompasses 40 years of Dow-Key’s team experience in the design and development of electromechanical RF switches with very demanding specifications and supporting challenging environments. It is intended for microwave instrumentation and modern automated test systems for high accuracy and performance. Extended operating life, outstanding RF performance and repeatability minimizes the cost of ownership by increasing test system uptime.
Now available for deliveries is a 1×6 bidirectional coaxial switch with an operating frequency from DC to 26.5 GHz, covering the typical 6 GHz test range for high-speed testing. The Reliant R461 switch is designed with a high isolation of 100 dB (up to 12.4 GHz) to maintain RF consistency between port-to-port testing.

The switch can operate in break-before-make (cold-switching) or make-before-break (hot switching) applications and has a switching speed of 15ms. Moreover, the Reliant R461JK switch can sustain a guaranteed insertion loss repeatability of 0.03 dB across the entire frequency band. It is offered with 50-ohm 2W terminated ports, latching actuators, SMA connectors, and optical position indicators while providing an extended life cycle where each position can switch a minimum of 5-Million cycles – a 5 X improvement from a typical multi-position switch.

A variety of control options are available including controlling the switch with +24Vdc coil voltage, or using TTL or CAN bus logic. For more sophisticated control solutions, the CAN bus interface can be converted to Ethernet or GPIB with RS-232 and USB controls by adding an external Dow-Key designed controller board.

Dow-Key also offers very extensive technical and application support providing value-added quality to an already robust product offering.
