Circuit Configuration

A novel coupled-line circuit configuration is proposed to design small-size dual-band Wilkinson power dividers. This proposed power divider consists of three sections of coupled lines and two isolation resistors. The analytical design theory is given and the electrical parameters analysis is provided. Six numerical examples are presented to demonstrate the flexible dual-band applications. To avoid a negative isolation resistor, a practical power divider operating at 1GHz and 2.2GHz with two positive-value resistors is designed. The calculated and full-wave simulated results verify our proposed idea. Keywords: Coupled-line, dual-band, power divider.

Good Agreement

A novel coupled-line structure is proposed to design dual-band and high-power Gysel power dividers with inherent impedance-transforming functions. Based on traditional even- and odd-mode technique, the analytical design methods in closed-form formula are obtained and the accurate electrical parameters analysis is presented. Due to the usage of coupled-line sections, more design-parameter freedom and a wider frequency-ratio operation range for this kind of dual-band Gysel powder divider are obtained. Several numerical examples are designed and calculated to demonstrate flexible dual-band applications with different impedance-transforming functions. A practical microstrip power divider operating at 2 GHz and 3.2 GHz is designed, fabricated, and measured. The good agreement between the calculated and measured results verifies our proposed circuit structure and analytical design approach.
