A Quick Crossover Design of a Three-Section Branch Line Structure

Abstract

This paper presents a quick method by using design chart to make a compact crossover design for planar circuit. The crossover is derived from the conventional three-section branch line structure. The proposed crossover planar circuit feature is implemented with moderate line impedance, compact layout and good performance. For verification, a single band crossover circuit works at 2.45GHz is fabricated and tested. Both simulated and measured results are found to be well matching with each other.
