ABSTRACT:
A phase shifter includes first and second series-connected resistor circuits each including first and second resistors and each interposed between each one of two input terminals and each one of two output terminals, and includes capacitors each interposed between each one of medium points of the series-connected circuits and each one of two output terminals. The phase shifter also establishes a relationship of RgRl=R.sup.2 where the value of the first resistor is Rg/2, the value of the second resistor is R, and the output resistance between the two output terminals is Rl.
