Special Considerations of the Developmentof the Contact System of the Microwave Switch with the Frequency Range up to 18 GHz

Abstract

The paper describes the development results and the construction of the high frequency contact system of the electromechanical microwave switch with the frequency range up to 18 GHz. The S-parameter measurement suggests that the achieved results are in line with the best in class competitive devices. The construction features the radially cut support beads, which enable simple and low-cost coaxial connector design that takes advantage of the monolithic center conductor design. The effects of the size of the radial cut on the effective dielectric parameters are researched using the quarter wavelength resonator method. The presented results of the research allow the accounting of the cut size on the microwave parameters of the switch. The presented construction of the developed resonator allows the coaxial support bead dielectric parameters control, implemented in the manufacturing process of the switch.
