Abstract
Devices and methods related to directional couplers. In some implementations, a coupler can include a driver arm and a coupler arm implemented relative to the driver arm to detect power of an RF signal. Portions of the driver and coupler arms can form an overlapping region, with at least one of the driver and coupler arms having a non-straight arm shape. The overlapping region can include a non-zero lateral offset between the driver and coupler arms. In some implementations, a coupler can include a driver arm having input and output sides, and a coupler arm having input and output sides and implemented relative to the driver arm to detect power of an RF signal. The coupler can further include a phase-shifting feature implemented with respect to at least one of the driver and coupler arms to reduce phase difference of power ripples associated with the coupler.
