ABSTRACT:
An electronic microwave calibration device provides an electronic load connected to each of two ports of a vector network analyzer. The load comprises a plurality of PIN diodes interconnected by transmission line. Each of the diodes are biased to generate different loads or conditions at each of the two ports. A control computer controls the biasing of diodes according to a predetermined procedure and compares impedance values measured at each of the two ports by the network analyzer to known values stored by the control computer. The control computer thereby derives calibration coefficients that are stored in the network analyzer and used by the network analyzer in performing further measurements.
