Abstract:
A load line type phase displacement unit, comprising:a main line unit comprising a main line having a characteristic impedance Z.sub.0 and an identical impedance Z.sub.c and a plurality of main line stubs having said impedance Z.sub.c of said main line and an identical impedance and being capable of changing a phase difference of an input signal; anda sub-line unit comprising a plurality of sub-line stubs having an impedance which is identical with said characteristic impedance Z.sub.0 of said main line and a sub-line which is connected in parallel with said sub-line stubs for compensating for error information based on a malfunction of the main line unit, wherein said main line stub has an associated length value, said length values of said main line stub with respect to the impedance being determined by the following equations B.sub.s1 and B.sub.s2 when the impedance Z.sub.1 and the characteristic impedance Z.sub.0 are identical; ##EQU2## where, Y.sub.0 denotes the reverse value of the characteristic impedance Z.sub.0, X.sub.r denotes a reactance value in the reverse bias state of a switching device, X.sub.f denotes the reactance value of the width component between a plurality of main line stubs, and X.sub.p denotes the reactance value of the length component of the main line stubs.
