Abstract
This paper presents the design and measured performances of an unequal dual-band power divider using lumped elements. After the divider is designed using the conventional single band Wilkinson topology with lumped elements, we obtained the dual band characteristics with filter conversion method. This design method has the features of compact size and easy fabrication, because the high impedance transmission line realizes the lumped elements of equivalent circuit. As an example, an 2:1 divider has been designed and measured at 880 MHz and 1650 MHz in order to show the validity of the proposed unequal divider. The measured performances of the unequal power divider agree with the simulation results.
