This paper describes the design of a 10 dB unfolded Lange coupler for operation at centering frequency of 5.8 GHz. The coupler is designed using the EDA software that has tuning and optimization features. The coupler is designed to have a coupling factor of 10 � 0.5 dB. in the design, microstripline...
