Automatic Microwave Network Analyzer Calibration by Reference to a Transmission-Line Standard with Applications to Characterization of Adapters, Devices, and Coaxial Lines with SMA Connectors.
Abstract
This dissertation describes the development of new techniques for calibrating a microwave automatic network analyzer (hereafter ANA) for complex reflection measurements. These techniques promise significant advantages for miniature connector systems. They include the use of an experimentally-derived characterization of an APC-7 open-circuit termination as a high-reflection calibration standard, adapter correction based on low dissipative losses, and a length of transmission line instead of a sliding load or fixed termination as a low-reflection standard. Gains afforded by these new techniques are reduced operator intervention during calibration, less wear of the measurement port connectors, lower equipment and maintenance costs, and calibrations referenced to standards truly relevant to the interconnecting transmission medium. Computer memory requirements are increased, but the cost of the increase is insignificant compared to the cost of microwave instrumentation. Slightly longer calibration times are offset by reduced demands upon operator skill. Methods of extending these calibration techniques to full two-port measurements will be discussed. (Author)
