A Novel Power Divider Design With Enhanced Spurious Suppression and Simple Structure

This paper presents a novel design of a microwave power divider with enhanced spurious suppression. The proposed circuit features simple implementation with moderate line impedance, flexible layout design, and extended stopband bandwidth with three controllable transmission zeros. Moreover, explicit closed-form expressions are available for the evaluation of circuit parameters. For verification, the simulated and measured results of a 1-GHz power divider implemented on microstrip are shown.
