Abstract
Systems and method are provided for making a balun's operational bandwidth tunable around multiple distinct center frequencies by using switches to vary the balun's dimensions. An embodiment of the present disclosure uses a pass gate structure for the switches, and the switches connect additional lengths of line in or out of the balun to change its frequency response. A balun in accordance with an embodiment of the present disclosure is able to switch its response between 2 or more adjacent bands by switching additional length of lines in and out of the balun's core windings.
