BAGLEY POWER DIVIDER WITH UNIFORM TRANSMISSION LINES FOR ARBITRARY POWER RATIO AND TERMINATED IN DIFFERENT IMPEDANCES

By Y. Yoon and Y. Kim

Abstract:
This paper presents an unequal-split Bagley power divider that consists of uniform transmission lines and is terminated at different impedances. This divider should be only adjusted by altering the length of the transmission lines. Such alteration of the transmission lines will result in an arbitrary power ratio between output ports. The Bagley divider consists of uniform transmission lines of same characteristic impedance value despite different impedances for input and output port termination. For analysis, two Bagley dividers are considered, one 3-way and one 5-way divider, both with arbitrary power ratio and arbitrary termination impedances. A good agreement can be observed between the simulated and measured results.
