A Multireflect-Thru Method of Vector-Network-Analyzer Calibration
Arkadiusz Lewandowski, Wojciech Wiatr, Nate Orloff, James Booth
We present a new method for two-port vector-network-analyzer calibration which uses multiple offset-reflect standards and a flush thru connection. Offset-reflect standards consist of sections of the same uniform transmission-line with different lengths, which are terminated with the same highly-reflective load. The unknown propagation constant of the transmission line and the load reflection coefficient are then determined simultaneously with the vector-network- analyzer calibration coefficients. We compare our method with the multiline thru-reflect-line method, and show that both methods yield similar results. Our new multireflect-thru method is solely based upon dimensional parameters of the calibration standards. Therefore, like the multiline thru-reflect-line method, it can be used to establish a traceable vector-network- analyzer calibration, Thus, the multireflect-thru method constitutes an alternative to the multiline thru-reflect-line calibration in environments in which the use of transmission lines is troublesome, such as in the case vector-network-analyzers with very small coaxial and waveguide connectors.
