Abstract :
Authors have studied a new interferometer based on coplanar strips (CPS) delay-line for application in a 5-6 GHz Instantaneous Frequency Measurement (IFM) system. The interferometer uses two-way Wilkinson power dividers connected to two CPS lines with different signal delays. This interferometer presents smaller dimensions when compared to other designs. A full wave EM simulator is used to obtain the frequency response for device. Simulated responses are presented and compared to theoretical curves.
