A simulation and experimental study of a directional coupler with transformers on ferrite rings has been carried out. The operating frequency range is from 100 to 500 MHz. The directional coupler was modeled in the Microwave Office application package. An experimental study was carried out using a vector analyzer of the type "Overview-103". The frequency dependences of the working attenuation and transient attenuation are obtained. The directional coupler can be used in transmitting and measuring technology.
