The Microstrip Device of Cross Redundancy 2 × 3 (3 × 2) for Onboard Equipment of a Command and Measurement System

The paper considers the types of microstrip devices of cross redundancy with the dimension 2 × 3 (3 × 2) for onboard equipment of a command and measurement system from the point of view of meeting the basic requirements applied to them. The new type of a microstrip power divider based on combination of the Lange bridge and directional Lange coupler and Wilkinson power divider is offered. The principle of its action is considered and design characteristics are given. The advantages over the known devices of this class are shown: the maximum transmission factor is −4.76 dB, isolation between the inputs is not less than 28 dB, VSWR of the inputs and outputs is not more than 1.4 dB in a frequency band of 12 %, and compactness and relative simplicity of a design.
