In one embodiment, an apparatus for transmitting and receiving wireless communications is provided. A balun is coupled to an antenna. The antenna transmits and receives radio frequency signals. The balun includes a first inductor including a first set of ports coupled to the antenna. The balun includes a second inductor with a second set of ports coupled to a power amplifier through a first circuit. The power amplifier transmits a first signal to the antenna. The balun also includes a third inductor with a third set of ports coupled to a low noise amplifier through a second circuit. The low noise amplifier receives a second signal from the antenna. The second set of ports is coupled to the first circuit and the third set of ports is coupled to the second circuit. Also, the first circuit is separate from the second circuit.
