Abstract

PURPOSE:To obtain a miniature infinite phase shifter featuring a reduced insertion loss by providing two pairs of variable phase shifters containing the finite phase shift amount and then switching these two pairs of phase shifters alternately under a fixed condition. CONSTITUTION:The infinite phase shifter consists of the following units: switch 3 to vary the distribution ratio of the signals supplied to signal input terminal 1; a pair of phase shifters 5 and 6 which are connected to each output of switch 3 with the finite variable range; and switch circuit 4 or compounder 8 which compounds the output of shifter 5 and 6 and then delivers the composite output to output terminal 2. In such phase shifter, the signal amplitude a and b which pass through shifter 5 and 6 are referred to as a and b with the phase difference theta between both signals respectively. And a switching action is given so that a fixed relation may be satisfied for a<2>+b<2>+2ab costheta. In that case, the phase shift amount of 5 and 6 can be controlled by application of the binary signal.
