Abstract
An adjustable antenna interface includes a single-ended to differential conversion circuit, an adjustable impedance matching circuit, an RF differential switch, and an input. The single-ended to differential conversion circuit converts inbound RF signals from single-ended signals to differential signals and converts outbound RF signals from differential signals to single-ended signals. The adjustable impedance matching circuit provides an impedance based on an impedance control signal. The RF differential switch provides the differential outbound RF signals from the IC to the single-ended to differential conversion circuit in accordance with a first antenna control signal and provides the differential inbound RF signals from the single-ended to differential conversion circuit to the IC in accordance with a second antenna control signal. The input receives the first antenna control signal, the second antenna control signal, and the impedance control signal from the IC.
