ABSTRACT:
This invention covers a phase shifter-equalizer circuit including a purely resistive impedance, a purely reactive impedance, at least one of which adjustable, and a phase inverter device, which permit to adjust in a continuous way the phase between the output current and the input current, while maintaining the amplitude of the output current constant and substantially equal to the amplitude of the imput current versus phase and group delay variations between the two currents. Furthermore, continuous phase adjustment is achieved by adjusting one only parameter of the circuit.
