Abstract

In this Major Qualifying Project we were tasked by our project sponsor, Skyworks Solutions Inc., to redesign a 90-hybrid coupler with the center frequency of 1.9GHz. The sponsor’s requirements for the new design were to increase the bandwidth and decrease the device area. Both of these requirements were met by developing a theoretical model and were then validated by simulations in Agilent’s ADS. Additionally Ansys’ HFSS was used to model the new design in a 3-D environment where the electric and magnetic radiation fields can be studied. This was a necessary step in order to develop a model accounting for interference originating from the device. The final design yielded a bandwidth increase of 150% with an area reduction of 63%.
