FIELD: radio engineering.SUBSTANCE: invention relates to microwave radio engineering and can be used for alignment of amplitude-frequency characteristics (AFC) microwave paths in operating frequency range. Improved matching in wide frequency range and high value of change of attenuation in range of frequencies at small dimensions. Micro strip amplitude corrector contains dielectric substrate on one side of which there is metal base, and on other side is first conductor, ends of which are input and output of corrector, and second conductor, one end of which is connected to first conductor through first resistor, and second is open, ends of first conductor are connected via second resistor, wherein lengths of sections of first conductor between points of connection of first and second resistors are identical and equal to length of second conductor and wave impedance of micro strip line formed by first conductor between connection points of second resistor more resistance input and output. Introduction of second resistor and connection between ends of first conductor allows at small dimensions providing matching in entire frequency range and any depth of correction of up to complete absorption at frequency correction.EFFECT: invention provides improved matching in wide frequency range and high value of change of attenuation in range of frequencies at small dimensions.1 cl, 3 dwg |
