Abstract: The passive devices are most commonly used in radio technology and power dividers are one among them. These power dividers are used to split the power and combine the power. It is a passive device used to couple a defined amount of power in a transmission line from one port to another port. Wilkinson power divider is implemented using various technologies like micro stripline technology, Coupled Line technology and strip line technology. In this paper, the design of 3dB Wilkinson Power Divider(WPD) to split the power equally & unequally at the output ports by using microstrip line technique and Coupled Line technique is proposed. This is useful mainly for mobile applications which has the operating frequency of 915MHz. The simulation is done using Advanced Design System (ADS) tool. Some of the performance parameters like return loss, isolation loss & insertion loss are measured in terms of scattering parameters.
