ABSTRACT:
An ultra-broadband balun is provided. The balun comprises: a first unbalanced transmission line comprising a first ground trace and a signal trace; and a balanced transmission line comprising a first and second signal trace, wherein the first signal trace of the balanced transmission line is connected to the first ground trace of the first unbalanced transmission line and the second signal trace of the balanced transmission line is connected to the signal trace of the first unbalanced transmission line, wherein a first capacitor is disposed in series with one of the first ground trace of the first unbalanced transmission line and the first signal trace of the balanced transmission line.
