The quadrature signal generator is widely used in devices such as the quadrature modulator and image rejection frequency converter. An RC polyphase network is commonly used as a quadrature signal generator because of its simple structure and perfect linear performance. This study derives explicit transfer functions for the RC polyphase network based on the complex signal properties and the matrix theory. Moreover, build-related parameters are determined to analyze the I/Q amplitude and phase balance characteristic of the RC polyphase network, thus providing a theoretical guideline for the design of a high-balance quadrature signal generator.
