This Reflectometer Bridge features reflection measurements covering from 40MHz to 18GHz with one directional device can be made with the reflectometer bridge.

Operation of this type of directional device is based on principles of the resistive wheatstone bridge extended to microwave frequencies.

When three bridge arms are 50ohms, the voltage across corners of the bridge is directly proportional to the reflection coefficient of the device connected in the fourth arm.

Equivalent directivity is then a measure of how well the bridge circuit is balanced with a 50ohms termination connected.

The high equivalent directivity achievable over wide bandwidths makes the bridge configuration attractive.
