Abstract
Directional couplers having a chain configuration and devices incorporating same. In some implementations, a chain coupler assembly can include a plurality of couplers each having a driver arm configured to route a respective RF signal and a coupled arm disposed physically proximate to the driver arm to detect a portion of power of the respective RF signal. Portions of the driver arm and the coupler arm can form an overlapping region. At least one of the driver arm and the coupled arm can have a non-straight arm shape, and the coupled arms of the plurality of couplers can be connected together in series.
