ある。The waveguide 12 in FIG. 1 is not required to be compared with the conventional circuit function, but can be used for further increasing the number of functions. Although the above description has been made in the form of signal division, it is apparent that the circuit can be used as a signal combining circuit by reversing the input / output relationship.
However, in that case, the two input signals in FIG. 1 must be in phase. In addition, it is clear that the arcuate waveguide 21 may be a curved waveguide, and it is also clear that installing a choke for blocking microwaves is effective.
