Mixed circuit applied to the signal distribution

Published:2011/8/7 5:17:00 Author:Sophia | Keyword: Mixed circuit, signal distribution | From:SeekIC

In the high-frequency circuits, signal distribution using the hybrid circuit is shown in the figure. The so-called hybrid circuit is to achieve the coupling between specific points, while the other points are insulated. Here, it is a experiment against the hybrid circuit among A, B, C, let C → A and C → B signal pass, A → B and B → A will be separated.To simply speaking, in this circuit, A and B will not interfere in each other, and form coupled circuit with C point together. In the hybrid circuit a dual winding coil is used. Here FT-82-43 (25T × 2) is used as experiment. If the surrounding impedance setting is not correct, effective separation will not be acheived.
