Highly Flexible Uniplanar Dual-Band Power Divider for Arbitrary Source and Load Impedances

Abstract

In this paper, a dual-band impedance transforming power divider is investigated for all types of impedance environments at its ports, irrespective of the locations of the ports. The intuitive design approach utilizes conventional single-band Wilkinson Power Divider (WPD) architecture to provide superior dual-band performance with arbitrary port impedances. The proposed power divider also accords a high degree of design flexibility with high frequency ratios (r) and impedance transformation ratios (k). The presented concept is evaluated and verified by design examples and measurements with a fabricated prototype. The agreement between the simulation and measurement results validates the working of the proposed architecture with arbitrary source and load port impedances at two arbitrary design frequencies.

Design of Three-mode Filtering Power Divider for Ship Anti-signal Interference

“…Power divider and bandpass filters are indispensable passive components in modern wireless communication systems [4][5][6][7][8][9]. By convention, these two devices take up too much space in the RF transmitting front-end system.…”
