Abstract

In this paper, a new dual band balanced-to-balanced power divider is proposed. By using the dual frequency 90° phase shifter based T model, the proposed balanced-to-balanced power divider can be deduced. By using the method in our previous work, the dual band balanced-to-balanced power divider could be designed with 1:1 power division. This balanced-to-balanced power divider is implemented on microstrip structure. Comparing the results calculated in analytical method with that simulated by the full-wave electromagnetic simulator, and that measured by the network analyzer, the final results show that they have a good mixed mode performance. The pass band 1 is from 2.395 GHz to 2.550 GHz, and the pass band 2 is from 5.245 GHz to 5.30 GHz. The maximum isolations for pass band 1 and pass band 2 are 17.8 dB and 17.6 dB, respectively.
