Microwave active phase splitters for quadrature demodulators

Abstract

The methods of correction of the phase angle error of the phase splitters (PS) of microwave band based on the differential stage designed for quadrature demodulators of the modern communication systems are suggested. The synthesis strategy of circuits of correction of the second order providing reduction of the amplitude-dependent phase shift up to 1-2 degree between the output signals of PS in the frequency band up to 6÷8 GHz are given.
