Abstract: A communication device includes a power amplifier that generates power signals according to one or more operating bands of communication data, with the amplitude being driven and generated in output stages of the power amplifier. A number of capacitive digital analog converter (CDAC) cells of a power amplifier can be sized to provide defined power signals along a signal path. In response to an optimization component that is coupled to a CDAC cell of the plurality of CDAC cells operating in a high efficiency enable mode and the CDAC cell being powered off in an off mode, the optimization component can increase a power efficiency of the power amplifier by reducing an impedance of an output capacitor of the CDAC cell.

Abstract: A signal coupling system may include a directional coupler that includes a first conductor and a second conductor. The first conductor may include a first end and a second end and may be generally arranged along a first plane. The second conductor may include a third end and a fourth end and may generally be arranged as a plurality of windings along a second plane. The signal coupling system may also include a transceiver, electrically conductively conducted to the first end; and an antenna, electrically conductively conducted to the second end. The second conductor may be configured to generate a coupling with the first conductor when the first conductor conducts an electric signal, such that the coupler conducts a first electrical signal from the first end to the second end at a second power, and conducts the electrical signal via the coupling to the third end at a third power.
