Abstract: The design, development, and testing of a transformer to convert an unbalanced to a balanced transmission line are described. Application of known principles has resulted in a transformer of broad frequency range. There is, also, a brief mathematical explanation of the theory involved in the procedure. An impedance match with a voltage standing wave ratio of 2:1 or less was obtained. Although two 5%ohm dummy loads were used in the design, application of the transformer with loads which have a mismatch of not greater than 2:1 voltage standing wave ratio proved satisfactory.
