Ural Federal University students have successfully realized an RF miniaturized branch-line coupler using the NI AWR Design Environment™ platform, inclusive of Microwave Office circuit and AXIEM 3D planar electromagnetic (EM) simulators.
The aim of the design project was to reduce the size of a 3 dB branch-line coupler as much as possible without losing its performance in isolation, imbalance and operating bandwidth. The students were further challenged to design the coupler based on low-pass microstrip filters instead of conventional transmission lines in order to achieve a more compact layout.
