<p>PURPOSE:To prevent deterioration of impedance between each terminal of 4-distribution equipment and a coupling loss between the terminals by connecting two following stage 2-distribution transformer at both edges of a secondary side winding of a preceding stage 2-distribution transformer for forming a 4-distribution configuration and then placing a matching transformer at the preceding stage side of the following stage 2-distribution transformer. CONSTITUTION:Matching transformers 16 and 17 for matching each terminal of a preceding stage 2-distribution transformer 10 which distributes signal from a matching transformer 15 for matching with an electronic circuit to be connected to a front stage into two parts with a following stage 2-distribution transformers 11 and 12 are provided. Thus, impedance matching is performed so that each terminal of the front 2-distribution transformer 10 and the following stage 2-distribution transformer 11 and 12 are matched by the matching transformer 16 and 17 which are provided at the preceding stage of the following stage 2-distribution transformers 11 and 12 even if a mismatching electronic circuit is connected to the preceding stage of the matching transformers 16 and 17 and a mismatching state occurs between each terminal of the preceding stage 2-distribution transformer 10 and the following stage 2-distribution transformers 11 and 12.</p> |
