Abstract
A transformer device of a double-balanced mixer includes a rectangular seat member and first and second transformers aligned side by side in a lengthwise direction on a top surface of the seat member. Support members project from the top surface of the seat member to position and secure the first and second transformers along the top surface. A plurality of pin terminals extend from a bottom surface of a seat member and are adapted to project through through-holes provided in a circuit board of the double-balanced mixer. Input and output wires of the first and second transformers respectively extend along recesses formed in the sides of the seat member for coupling to the pin terminals.
