Abstract: Disclosed is a device including a first line, a second line including a first section disposed on a first side of the first line and a second section disposed on a second side of the first line, the second side being opposite to the first side and the second section being separate from the first section by a distance, and at least one bridge electrically connecting an end of the first section with an end of the second section and extending across the first line. The device may be a directional coupler that achieves significantly higher directivity than conventional directional coupler structures, and hence, improves power detection accuracy.

Abstract: A method, a phase shifter, and a user equipment (UE) are disclosed for transmitting and receiving signals in a phased array. The method includes receiving, by a balun of a phase shifter, a transmission single-ended input signal at a single-ended side of the balun and generating a transmission differential input signal at a differential side of the balun, generating, by a differential quadrature coupler of the phase shifter, a transmission in-phase signal and a transmission quadrature signal, based on the transmission differential input signal, and combining, by a differential attenuator of the phase shifter, the transmission in-phase signal and the transmission quadrature signal into a differential phase-shifted output signal.

Abstract: A closed-loop power control (CLPC) system is disclosed that includes a first signal path for a first polarization and a second signal path for a second polarization. The first signal path includes a first power amplifier, a first output power detector configured to detect a first output power level of the first power amplifier, and a first processor configured to determine a first analog gain for a first controller and a first gain for a first digital-to-analog converter based on a first accumulated error between the first output power level and a target Effective Isotropically Radiated Power. A second processor is configured to set a first variable gain of a first variable gain amplifier coupled to an input of the first power amplifier. The CLPC can be configured to control the gain of the first signal path separately or as one signal path.
