Abstract: A phase shifter may include a cavity body, and a fixed circuit board and a phase shift unit that are located inside the cavity body, and the phase shift unit being capable of moving relative to the fixed circuit board. A power division circuit is disposed on the fixed circuit board. The power division circuit includes an input end, a main feeder, a node, at least two output ends, a filtering stub, and at least two output circuits. The main feeder is electrically connected between the input end and the node. The filtering stub is electrically connected to the main feeder, and the filtering stub is in an open-circuit state. The at least two output circuits are respectively electrically connected between the node and the at least two output ends. The phase shift unit is disposed in correspondence with the at least two output circuits.

Abstract: A BLUETOOTH connection method includes an electronic device establishing basic rate (BR)/enhanced data rate (EDR) connection to an accessory device. The electronic device determines that the electronic device supports a dual-mode connection and that the accessory device also supports the dual-mode connection. The dual-mode connection includes the BR/EDR connection and a BLUETOOTH Low Energy (BLE) connection. The electronic device disconnects the BR/EDR connection to the accessory device, and establishes the BLE connection to the accessory device.

Abstract: The present disclosure relates to phase shifters, antennas, and base stations. One example phase shifter includes a cavity, a built-in printed circuit board (PCB), and a stress relief portion. The stress relief portion is connected to the PCB, and the stress relief portion is configured to reduce a stress generated due to different coefficients of thermal expansion (CTE) of the cavity and the PCB.
