Abstract

PURPOSE:To obtain a waveguide-form attenuator which performs attenuation on a basis of the phase difference between transmission waves transmitted through two lines, by using no resistor absorbing the transmission power in the attenuation quantity determining part and forming the two transmission lines for transmission input. CONSTITUTION:Directional couplers 10 and 11 where, for example, holes smaller in comparison with the guide wave length as coupling elements 14 are formed at prescribed intervals are provided on the common wall of main waveguide 12 and auxiliary waveguide 13. First waveguide 15 having line length la is connected between main waveguides 12, and second waveguide 16 having line length lb (lb>la) different from line length la of first waveguide 15 is connected between auxiliary waveguides 13, and resistive terminators 17 are connected to the end of auxiliary waveguides 13.
