Abstract

PURPOSE:To minimize the insertion loss of the reception circuit by connecting one end of both the secondary winding and the intermediate terminal of the auto-transformer to the branch terminal each and then grounding the other end of the transformer and the resistance each. CONSTITUTION:One end of the main conductor and the auto-transformer is connected to the input terminal each; the other end of the main conductor is connected to the output terminal; and one end of the intermediate terminal of the auto-trans former and the secondary winding is connectd to the branch terminal each. Then the other end of the auto-transformer and the resistance is grounded each. As a result, the insertion loss of the reception circuit can be minimized.
