Abstract

Abstract:

Design of a coupled line with a pair of isolation stubs is presented. Dual-band operation in the Wilkinson power divider can be achieved and also, the overall structure of the power divider can be simplified. Compared with the power divider directly connected by an isolation resistor, the one consisting of isolation stubs reduces the parasitic effects between transmission lines. A 1.0GHz, 2.5GHz dual-band Wilkinson power divider is designed and processed. It is proved that simulation results agree with the experimental ones and the power divider works well.

Key words: wide band-ratio, dual-band, wilkinson power divider, coupled line
