Applied TRL Calibration Technique Using ABCD Matrices for Bended Access Ports
Current Journal of Applied Science and Technology,
Calibrating network analyzer is still an issue for bended access port devices (devices with accesslines at an angle to conventional transmission lines). Bended accesses can give additional errors which are taken into account by using a new design standards of Vector Network Analyzer (VNA) calibration. This Thru-Reflect-Line calibration technique is computed from ABCD parameters that easily allow to remove the bended port effects. This approach is based on the assumption that the Vector Network Analyzer error boxes can be considered as passive system. Furthermore, the method can be applied for de-embedding devices with bended accesses. This calibration and de-embedding technique could be applied, for example, to a coplanar circulator or a power divider measurement which have access lines at 120° from each other.
