Title: Phase shifter
Inventor: TANAKA YASUHIRO
IPC: H03H11/20
Filed: 1986-08-11
Abstract: PURPOSE:To obtain a phase shift amount close to 360 deg. immune from output fluctuation byt providing a series circuit comprising a capacitor and an inductor for phase shift setting and the 2nd series circuit comprising resistors and connected in parallel with the 1st series circuit. CONSTITUTION:A signal subject to phase shift is outputted to the 1st series circuit 2 and the 2nd series circuit 7 via a buffer amplifier 1. The phase of a difference (V1-V2) between the potential V1 at a connecting point of resistors 21, 22 and a potential V2 at a connecting point at an inductor 7 and a resistor 73 is 180+2tan<-1>(omegaL/R), where R is a resistance of the resistor 73. In bringing the resistor R to '0', the phase shift of the potential difference (V1-V2) with respect to the capacitance C of a variable capacitor 71 changed from '0' to infinite is 360 deg.. Since it is difficult to bring the capacitance of the variable capacitor 71 to '0' or inifinite, even when the minimum value C1 of the capacitance is larger than '0' and the maximum value C2 is definite, a larger phase shift is obtianed with the decreased resistance R by deciding the minimum value C1 and the maximum value C2 in the relation of (1/omegaC2)<omegaL<(1/omegaC1).
