Abstract :
A novel planar tri-band power divider using step-impedance resonator with band-pass response is proposed in this paper. The topology of the circuit, different from conventional Wilkinson power divider, is the couple lines and resonators instead of the transmission lines. It can provide good isolation, good amplitude balance simultaneously at three arbitrary frequencies and direct current (DC) block characteristic. The proposed structure is analyzed and simulated. The validity of the design is demonstrated by experimental results on a 930/2300/3600 MHz power divider.
