A Broad-Band Homodyne Network Analyzer with Binary Phase Modulation (Short Paper)

An automatic homodyne network analyzer system using cascaded binary phase shifters is described which operates over the full X-band with a high dynamic range due to an auxiliary modulation and linear detection technique. A general analytic solution of the complex nonlinear system equations is given which allows the use of a coupled modulator/phase shifter structure. Measurement results are reported.
