ABSTRACT:
An input signal is applied to a first phase shifter whose phase shift amount-vs.frequency characteristic is a square-law characteristic, then the output from the first phase shifter is amplified by an amplifier, and the amplified output is applied to a second phase shifter which has a phase shift amount-vs.-frequency characteristic that is substantially inverse to that of the first phase shifter, thereby obtaining an amplified output signal from the second phase shifter.
