Abstract
A directional bridge for characterizing a signal reflected from an RF device under test (DUT) the bridge comprising: a differential signal source with two antipodal outputs wherein the first output is connected to a reference termination, and the second output is connected to the DUT, and at least one equal-ratio resistive divider wherein one side of the resistive divider is attached to the first output, and the second side of the resistive divider is connected to the second output and the middle point of the resistive divider is connected to a receiver, wherein the at least one equal-ratio resistive divider is configured to provide a separated forward and reverse signals by canceling a differential mode of a transmitted signal at the bridge.
