“…As θ increased from 10° to 90°, the circuit circumference becomes larger; and bandwidths of S 22 and S 32 become wider for both series and parallel RC components, where, when θ = 90°, the proposed WPD becomes conventional WPD . Detail design parameters of proposed WPD are shown in Table , the design parameters of former WPD are also listed in Table for comparison under the same conditions. Compared with the former WPD in Refs.…”

By using complex isolation component, the proposed Wilkinson power divider occupy smaller area than that of conventional Wilkinson power divider. General design equations for complex isolation component are derived from even‐ and odd‐mode analysis. Various RLC circuits are chosen to realize complex isolation components, respectively. Considering the bandwidths of S22, S33 and S32, inductors in RLC circuits are omitted to get the widest bandwidths and easy fabrication. Compared with Trantanella's work, the proposed power divider provides wider bandwidths of S22, S33 and S32, and smaller capacitances under the same conditions, furthermore, the resistor in parallel RC circuit is constant value and suitable for industry applications. In experiment, one circuit was fabricated with parallel RC isolation component, experimental results showed good agreement with theoretical results. © 2016 Wiley Periodicals, Inc.

This paper introduces a modified Wilkinson power divider that uses uniform transmission lines for various terminated impedances and an arbitrary power ratio. For the designed power ratio, the proposed divider changes only the electrical lengths of the transmission lines between the input and output ports, and those between the output ports and the isolation resistor. In this case, even when various termination impedances of the ports exist, the divider characteristics are satisfied. To verify the feasibility of the proposed divider, two circuits were designed to operate at a frequency of 2 GHz with 2:1 and 4:1 power splitting ratios and various terminated impedances of 40, 70, and 60 Ω for one circuit, and 50, 70, and 60 Ω for the other. The measurement and simulation results were in good agreement.
