Frequently Asked Questions

Q: What does SPDT mean in the context of this RF coaxial switch?

A: SPDT stands for Single Pole Double Throw. It means the switch has one common input port and two output ports, allowing the RF signal to be routed between two different paths. This is a fundamental configuration used in antenna switching, signal routing, and test & measurement systems.

Q: Is this RF switch suitable for use above 3GHz?

A: While the Radiall R570315000 is rated DC to 3GHz, actual testing on this unit has demonstrated performance up to 18GHz. However, for applications above 3GHz, users should conduct their own verification, as performance beyond the rated specification is not guaranteed by the manufacturer.

Q: What condition is this switch in?

A: This unit is a second-hand original disassembled item. It has been fully performance-tested and confirmed to operate normally. It is not a new-in-box product. Buyers who require a factory-sealed unit should note this before purchasing.

Q: What voltage is required to operate this switch?

A: The Radiall R570315000 operates at a working voltage of 24V DC. Ensure your control circuit or power supply matches this specification before installation.
