This paper presents design and analysis of Dual Band 2-way Equal/Unequal power dividers at frequency 325 & 650 MHz using ArlonTC350 substrate. The proposed power divider can operate at two frequencies without reactive components. There is structure of the power divider and the formulas used to determine the design parameters have been given. A scheme is proposed for the dual-band operation of the power divider/combiner, which has simple structure and is suitable for distributed circuit implementation. The dual band operation is achieved by attaching two central transmission line stubs to the conventional Wilkinson divider and an isolation resistor. For verification, dual band power dividers operating at 325 and 650 MHz are fabricated; the experimental results show that the designed equal/unequal power divider fulfills all the features of a conventional Wilkinson power divider. Finally, the EM simulated results are validated with the characterization of microstrip power dividers at 325 & 650 MHz. After that optimization has also done using AWR to improve the return loss and isolation. The measurements carried out on the fabricated PCB comply with the simulation results. The measurement results of this design provide an insertion loss, return loss (or VSWR) and isolation with the good result.
