Abstract
A standing wave ratio detection arrangement is disclosed. The arrangement includes a standing wave ratio detector and a controller. The standing wave ratio detector is configured to receive an isolated signal and a coupled signal and to generate a multi-bit return loss signal based on the isolated signal and the coupled signal in the analog domain using successive attenuation of the coupled signal. The controller is configured to determine a standing wave ratio from the return loss and to generate an antenna tuner control signal using the standing wave ratio.
