Abstract
An engineering design and implementation of bi-directional coupler are introduced, which operates within 500~2 700 MHz and supports the power of 200 W continuous wave.The main part of directional coupler adopts strip line structure,and the input and output ports use micro-strip structure,which are integrated into one module.The compensation techniques of inductor is used to poise the odd mode and even mode,and the design parameters of RF compensation circuit are obtained according to binary concept and capacitive compensation theory,which are simulated and optimized using Ansoft HFSS.The simulation results show that the designed coupler has high bandwidth,high power and high directivity and the specifications can meet technical requirements.关键词
