Abstract
A wide bandwidth R. F. vector bridge is provided which is made up of a housing and a microcircuit contained therein. The microcircuit includes a substrate having two opposing faces, and a patterned layer of conductive material on each face defining a reflection port area, a reference port area, and a test port area. A first impedance means provides a first impedance between the reflection port area and the reference port area, and a second impedance means provides a second impedance between the reflection port area and the test port area. Also included are a reflection port means for coupling the reflection port area to other electrical components, a reference port means for coupling the reference port area to a reference load, and a test port means for coupling the test port area to a device under test. The first and second impedance means, the reflection port means, the reference port means, and the test port means are arranged to provide equal times for signal transit between the reflection port means and the test port means and between the reflection port means and the reference port means.
