Claim 6:
7. A balun comprising:
a first winding having a first terminal coupled to an input, and a second terminal coupled to a reference potential terminal;
a second winding magnetically coupled to the first winding and having a first terminal coupled to a first differential output, a second terminal coupled to a second differential output, and a tap coupled to the reference potential terminal;
a first capacitor having a first terminal coupled to the input of the first winding and a second terminal coupled to the first differential output of the second winding;
a third winding magnetically coupled to the first winding and having a first terminal coupled to the reference potential terminal and a floating second terminal; and
a second capacitor having a capacitance approximately equal to the capacitance of the first capacitor having a first terminal coupled to a center tap of the third winding and a second terminal coupled to the second differential output of the second winding.
