Summary:Attenuators are widely used to create modern wireless communication systems. It is important to ensure the high quality of the transmitted signals so that the exchange of information takes place without loss. The use of differential attenuators in microwave equipment allows you to increase flexibility and expand the scope of the systems. The problem with providing high isolation with maximum signal attenuation and low attenuator losses with minimal attenuation is most difficult to solve. The presence of parasitic effects at microwave frequencies imposes certain difficulties in the design of attenuators. In the course of the study, methods of reducing losses with minimal attenuation and increasing maximum isolation based on the use of complementary differential attenuators, shunt resistors were determined using computer modelling. The methods' effectiveness is proven by achieving minimum losses of no more than 1.5 dB and maximum attenuation of at least 36dB.
