Abstract
Wideband baluns with enhanced amplitude and phase balance are provided. The wideband balun includes a first transmission line connected between a first port and a third port, and a second transmission line connected between a second port and a fourth port, and a third transmission line connected between the third port and a reference voltage, such as ground. To enhance phase and/or amplitude balance of the wideband balun, the wideband balun further includes a compensation structure operable to provide at least one of capacitive compensation or inductive compensation to balance the wideband balun. For example, in certain implementations, the compensation structure includes at least one of (i) a capacitor connected between the first port and the second port or (ii) a fourth transmission line connected between the first transmission line and the third port.
