- Abstract
- This paper proposes a miniaturized multi-section power divider with parallel resistor and capacitor isolation circuits. Each of the section transmission lines constituting the proposed multi-section power divider has a length less than a quarter wavelength and the impedance of the transmission lines can be controlled within a certain range while avoiding high impedance. In addition, each circuit connected between the transmission lines consists of a parallel resistor and capacitor to satisfy the matching and isolation characteristics between output ports. To validate the proposed power divider, two circuits at a frequency of 2 GHz were designed with two- and three-section dividers. In comparison to a conventional power divider, the proposed divider showed broadband performances with a small structure.
