A novel wideband Wilkinson divider using parallel branch lines

Abstract: A novel wideband branch line Wilkinson divider is proposed. Branch lines are introduced to replace multiple resistors used in the multistage Wilkinson divider to increase the bandwidth of a single‐stage Wilkinson divider. To demonstrate its performance, a modified single‐stage Wilkinson divider with four branch lines has been fabricated and measured. Results show that the measured input return loss, output return loss, and isolation are better than 12.4, 11.6, and 15 dB, respectively, across a 72% bandwidth fr… Show more

“…However, equal-split and output-input inverse polarity but output-output in-phase power divider are also greatly needed in the modulation system. Moreover, the coupled structures or the transition between different types of the transmission lines need to be carefully manipulated to avoid mismatching and multilayer PCB is expensive to be fabricated [9][10][11][12].…”
