A study of the directional coupler range 1-4GHz. The description of the construction on a symmetrical strip line with a lateral connection is given. The amplitude-frequency characteristics were simulated using the Microwave Office package. The model of the directional coupler is experimentally investigated, the following results are obtained: the working attenuation does not exceed 1.7 dB, the transient attenuation does not exceed 10 dB.

The article studies the power divider of 10-centimeter range. A description of the scheme and design of the power divider on the air-strip transmission line. The analysis of the amplitude-frequency characteristics of the power divider in the forward and lateral shoulders with the help of the Microwave Office package is carried out. The model of the power divider is experimentally studied, the following results are obtained: in the band from 2.4 to 3.7 GHz, losses do not exceed 4.3 dB, and the unevenness does not exceed 1.7 dB.
