Abstract
A balun including on the common-mode side, an inductive element in series with a first capacitive element between a first common-mode access terminal and the ground; and on the differential-mode side, two inductive windings in series having first respective ends defining differential access terminals and having second common ends connected to ground, second capacitive elements being respectively connected in parallel on the differential-mode windings.

A balun comprising:
- on a common-mode side, an inductive element in series with a first capacitive element between a first common-mode access terminal and ground;
- and
- on a differential-mode side, two inductive windings in series having first respective ends defining differential access terminals and having second common ends connected to ground,
- wherein second capacitive elements are respectively connected in parallel on the differential-mode windings, wherein the value of the second capacitive elements is selected to define an impedance on the differential-mode side at a second frequency different from a first frequency approximately centered on a bandwidth of the balun.

A balun comprising:
- a common-mode side including a first inductive element in series with a first capacitive element between a common mode terminal and a reference voltage;
- and
- a differential-mode side including second and third inductive elements having first ends defining respective differential-mode terminals and having second ends connected to the reference voltage;
- and second and third capacitive elements respectively coupled in parallel with the second and third inductive elements, wherein the first capacitive element has a value that defines an impedance of the balun at a first frequency and wherein the second and third capacitive elements have values that define an impedance of the balun at a second frequency different from the first frequency.
