A Power Reflection Technique for Characterization of High Quality Varactor Diodes

A new method for varactor diode characterization has been developed. As the quality of microwave varactors rapidly improves, a simple and accurate means of characterization has become increasingly important. The present methods for varactor characterization consist of either a "relatlve impedance" or a "transmission" technique. The commonly accepted varactor equivalent circuit is shown in Figure 1.
