Frequency Trimming

This paper presents the data for frequency trimming of the single port STW resona-tors in a frequency range of 500–1000 MHz by plasma chemical etching method. The main parameters of resonators after frequency trimming are given: frequency tolerance <±100·10–6, quality factor of 8600–9500, equivalent elements needed for use of the STW resonators.

. The calculation of nominal values of the matching device for the modified plasma chemical etching installation "Plasma 600T" was based on the estimated values of the discharge impedance (plasma). It turned out that for optimal performance, one can use a matching device consisting of two capacitors whose capacitances are: С1 [20; 1000] pF, С2 [4; 100] pF, and inductor with inductance 2,5 μH.
