Design of a Power Divider for Dual Band at 1.5GHz and 2.4GHz

In recent years, there are increasing demands for dual-band equipment due to the development of multiband technologies. Therefore, the conventional power divider is not suitable for dual-band applications. In recent time power divider is used for many applications which inspired me for doing a work on that topic .Within the RF and microwave community, power dividers have served a prominent role for years. The main function of a power divider is to split a given input signal into two or more signals as needed by the circuit/system .Another power divider application and the inspiration for this thesis work is for GPS and BLUETOOTH application. In this system a signal is either fed through an equal split power divider featuring a specific number of output ports, or a series of equal split power dividers. In recent time due to scope of multiband frequency dual band power divider play a nominant role .This research presents design and implementation of power dividers at frequency 1.5 GHz and 2.4GHz using FR4 substrate. Design parameters used in the design of power divider are input and output matching, insertion loss and isolation between the both output ports. The design parameters presented in graph on the simulation result from ADS2011.10 software simulation .The simulation and measurement results taken where the return loss is >-30db insertion loss is about -3.5dB and isolation between the output ports is -15db is achieved.
