Precision RF Shorts

Type RFS Precision Shorts have been designed to give as perfect a total reflection as possible when used in a 50 ohm system with SMA connectors. The reflection coefficient is typically .99 or better. Other connectors and impedance levels are also available.

These devices are used wherever a precision broadband total reflection is required with the phase reversal of an RF Short. Phase shift measure­ments, power measurements, reflectometer and many other experimental setups are adjusted and calibrated with these components. The distance from the short circuit to the connector reference plane may be adjusted to your specific require­ments.
