Characterizing a noninsertable directional device using the NIST uncertainty framework

Abstract

-We characterize and provide uncertainties for a noninsertable, directional device over a frequency range of 90 to 100 GHz using the NIST Microwave Uncertainty Framework in conjunction with a commercial vector network analyzer. Our device consists of a chain of components, including a coaxial-towaveguide adapter, a waveguide band-pass filter, a waveguide low-noise amplifier, a waveguide isolator, and a waveguide taper. With the aforementioned directional components, the wellknown adapter removal technique is not adequate on its own for characterizing our device. In this paper, we describe and implement our method, and propagate the uncertainties from the two required calibrations to the characterized device.

Millimeter-Wave Modulated-Signal and Error-Vector-Magnitude Measurement With Uncertainty

“…We characterized our 2.4-mm SOLT calibration kit by comparison to thru-reflect-line (TRL) measurements with the procedure described in [40] and [41]. This required building detailed models of each of the TRL calibration standards that included imperfections in the geometry of both the TRL calibration artifacts and the test ports we used, and propagating those uncertainties through the SOLT characterization and measurement process.…”

Developing models for Type-N coaxial VNA calibration kits within the NIST Microwave Uncertainty Framework

“…In this paper, we utilize the NIST Microwave Uncertainty Framework [6][7][8][9][10] to develop physical models of commercially available Type-N multiline TRL and OSLT coaxial calibrations kits, and then use the multiline TRL calibration to create a traceable measurement-based model of an ECU. The NIST Microwave Uncertainty Framework utilizes parallel sensitivity and Monte-Carlo analyses, and enables us to capture and propagate the significant Sparameter measurement uncertainties and statistical correlations between them [11].…”

“…In this paper, we utilize the NIST Microwave Uncertainty Framework [3][4][5][6] to develop physical models of commercially available 2.4 mm and 3.5 mm multiline TRL and OSLT coaxial calibrations kits. The NIST Microwave Uncertainty Framework utilizes parallel sensitivity and Monte-Carlo analyses, and enables us to capture and propagate the significant S-parameter measurement uncertainties and statistical correlations between them [7].…”
