Dow-Key® Microwave’s Hi-Repeatability Reliant Switches™ product line is economically priced to minimize impact to budgetary concerns and are designed to deliver its specified performance over the life of the switch.
Reliant Switches with a SPDT being the first RF switch in this series made available to the RF & test industry.
The Reliant Switch™ SPDT has a switching time of 15 ms and it is offered with a nominal power supply voltages of +12Vdc or +24Vdc. The switch can be controlled by applying ground to close the desired port, but it is also available to be controlled via TTL logic (by applying +5vdc to close a port or +0Vdc to open a port).Both Reliant Switch™ SPDT switch options can operate over a -25°C to +75°C temperature range and be stored between -55°C to +85°C. For antenna and radar related applications, the switch operates up to 15,000 ft and can be stored at 50,000 ft without any performance degradation.
