摘要

本文介绍了一种工作在全ka波段(26.5 - 40ghz)的纯差网络分析仪。该系统采用三个级联二进制移相器，并将调制rf信号下变频到基带，在基带由微型计算机进行处理。50 dB衰减时，相位测量误差小于2.5°，幅度测量误差小于0.5 dB。线性系统误差通过应用自动误差校正程序而减小。

A Computer Controlled Homodyne Network Analyser with Phase Shift Keying and Error Correction for 26.5 - 40 GHz

This paper presents a homodyne network analyser working over the full ka-band (26.5 - 40 GHz). The system employs three cascaded binary phase shifters and downconverts the modulated RF-signal to the baseband, where it is processed by a microcomputer. Measurement errors for 50 dB attenuation are less than 2,5° for the phase and 0,5 dB for the amplitude. Linear system errors are reduced by the application of an automatic error correction procedure.
