The calculation results of directional couplers with connection via the waveguide common narrow wall with a coupling factor of 3.0 decibels, directivity no less than 20 decibels, adjustment of coupling factor at 1 decibels are presented. The adjustment is carried out with the help of cylindrical plungers, moving inside of waveguides on the part of broad walls in the location of the connection slot, and prismatic plungers, moving in rectangular waveguides connected to narrow walls opposite to a slot of connection. The device as a magic tee with movable throttle pistons in Е- and Н-plane arms permitting to match any load is designed too. The calculations are executed for devices operating at frequencies of 2.797 and 1.3 GHz.
