The RF and microwave characteristics commonly used to define the performance of components are typically measured using a vector network analyzer. Since the packages of devices manufactured by Barry Industries, Inc. typically do not have coaxial connectors, the issue of the most appropriate calibration technique to utilize becomes critical. In this paper, the fixtures used and the calibration techniques employed are discussed along with the rationale for their selection. For components with coaxial connectors, commercially available VNA calibration kits are available. These calibration kits are available with traceability to well known standards agencies such as the National Institute of Standards and Technology (NIST). For devices with packages designed for direct integration with planar transmission lines such as microstrip, stripline, coplanar waveguide (CPW), etc., no such standards have been developed. Direct correspondence with NIST experts has resulted in identification of the TRL calibration as the de-facto standard and the OSLT and its derivatives as the preferred approximations in production environments.
