FIELD: physics. ^ SUBSTANCE: invention can be used in radio communication systems, radar and telecommunications in very low frequency ranges, ultrahigh and microwave frequencies. The discretely tunable resonator has a quarter-wave section of a regular transmission line connected to tuning sections consisting of a tuning capacitor and an electronic switch, capacitance values of all tuning frequencies Cs of the tuning sections, maximum allowable frequency tuning step öf, length of the section of the regular transmission line l0 and coordinates of points of connecting X1, X2,Ç, Xn the tuning sections to the section of regular transmission line with wave impedance are selected using a system of linear equations. ^ EFFECT: low cost of making a discretely tunable resonator on a section of regular transmission line. ^ 3 dwg |
