Abstract
PURPOSE:To reduce the size of the titled converter by constituting the titled converter by a 1st waveguide whose length of the H plane passes a desired wave but interrupts undesired wave having a frequency lower than that of the desired wave, a 2nd waveguide outputting a desired wave and an impedance matching device taking the impedance matching of them. CONSTITUTION:The cut-off frequency of the waveguide 8 is increased to pass a desired wave but the undesired wave of the frequency lower than that of the desired wave is cut off to eliminate the need for a band-pass filter. That is, the length of the H plane of the 1st waveguide 8 is decreased to increase the cut-off frequency of the waveguide thereby cutting off the undesired wave of the frequency lower than the desired wave frequency. Since the characteristic impedance of the 1st waveguide is higher, the impedance converter 9 is used to match it with the 2nd waveguide 10 for a standardized output. Thus, any band pass filter is not required and miniaturization is attained.
