Abstract

A novel planar three-way power divider is proposed. Based on the conventional planar microstrip coupled line technology, the proposed three-way power divider can modify a three-way Wilkinson power divider from a three-dimensional configuration into a two-dimensional one, meanwhile, to keep the length of the circuit to be lambda/4. The planar structure enables easy circuit design in printed circuit boards and monolithic microwave integrated circuits. The design concept and implementation are discussed. From the measured results, less than 4.8plusmn0.1dB of the three equivalent insertion losses, less than 19.5dB of the return loss, and better than 17.5dB of isolation at 2.4GHz can be achieved
