Abstract: An active quadrature signal generator produces poly-phase quadrature signals necessary in high frequency transmit and receive elements of a communication system. The quadrature signals are produced using the phase difference between a load representing a low-pass filter characteristic and a load representing a high-pass filter characteristic and the quadrature signal is then used in the differential structure to produce amplified signal having 4 quadrature phases. The device can reduce a loss characteristic of the signal and additional power consumption for compensating for it in a common poly-phase quadrature filter having only conventional resistors and capacitor.
