ABSTRACT:
An electrical circuit provides a constant phase shift between two output signals derived from a common input. The output signals are designed to provide a constant phase shift at constant amplitude over a very large frequency range. The common input is provided to both a non-shift channel and a phase-shift channel. The non-shift channel comprises a fixed attenuator circuit that provides a non-shifted output signal. The phase shift channel comprises a low-pass RC filter circuit that provides a phase shifted output signal. The two output channels are connected by a transformer phase detector that generates an error signal. The error signal is input to an operational amplifier that provides a phase-shift control signal to the RC filter circuit of the phase-shift channel.
