3. A balun, comprising:
circuitry configured to convert a single-ended signal received at an input node to a differential signal and to output the differential signal across a first output node and a second output node;
a first high-pass filter connected between the input node and the first output node;
a second high-pass filter separate from the first high-pass filter and connected between the input node and the second output node; and
at least one of a resistor connected between an input of the first high-pass filter and ground or a second resistor connected between an input of the second high-pass filter and ground.
