The modified quarter-wavelength resonator method for parameters control of the coaxial connector dielectric beads

Abstract

The paper describes the modification of the SRG-50-751 connector by means of the support bead material change. The modification is made in order to extend the operating temperature range of the connector, and may also reduce the VSWR of the connector. The modified coaxial quarter-wavelength resonator method is used for bead parameter control. The modification of the method increases the dielectric constant measurement accuracy and enables to measure specimens with different lengths. The method of dielectric loss tangent measurement of the beads is outlined in the article.
