7-PORT TYPE CORRELATOR, CALIBRATION METHOD THEREFOR, AND VECTOR NETWORK ANALYZER UNIT USING 7-PORT TYPE CORRELATOR

摘要

PROBLEM TO BE SOLVED: To solve such a problem (that measuring precision gests worse in|a1|<|a2|when a complex amplitude ratio W=a2/a1of two waves a2, a1is found) in a 6-port type correlator of a highly precise and a simple phase measuring system in an ultra-high frequency area and a light area. SOLUTION: This 7-port correlator constituted to be provided with two sets of the 6-port type correlators is provided by adding a reference port of the a2in addition to a port (reference port) for monitoring an amplitude value of the a1, and the complex amplitude ratio is restricted within a unit circle to realize highly precise measurement, by finding W=a2/a1in|a1|≥|a2|, and by finding W-1=a2/a1in the|a1|<|a2|.
