Coaxial Switch for RF Testing: Reliant™Source: Dow-Key Microwave Corp.
Dow-Key Microwave’s new Reliant SwitchTM is a 1x6 bidirectional coaxial switch with an operating frequency from DC to 26. 5 GHz, which covers the typical 6 GHz test range and beyond for high-speed testing. This switch is designed with a high isolation of 100 dB (up to 4 GHz) to maintain RF consistency between port-to-port testing. Moreover, the switch can sustain a guaranteed insertion loss repeatability of 0.03 dB across the entire frequency band. This coaxial switch has an extended life cycle where each position can switch a minimum of 5-Million cycles - a 5X improvement from a typical multi-position switch.
To meet a variety of test and measurement setups and signal switching configurations, the Reliant Coaxial SwitchTM is offered with latching actuators, position indicators, SMA connectors and with 50-ohm 2W terminated ports. It can operate both in break-before-make (cold-switching) or make-before-break (hot-switching) applications and has a switching speed of 15 ms. 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 externally a Dow-Key designed controller board.
