摘要： RF signal transmission devices for a base station antenna include a printed circuit board which has a dielectric layer, a metal pattern layer on a first main surface of the dielectric layer, and a ground layer on a second main surface of the dielectric layer. The metal pattern layer has a transmission line deformation section for enhancing the ability to withstand surge current, and the ground layer comprises a groove that is configured to at least partially compensate for the change in the characteristic impedance due to the transmission line deformation section. The RF signal transmission device can achieve good characteristic impedance matching whilst enhancing the capacity to withstand surge current. In addition, the RF signal transmission device can improve PIM performance. The present disclosure also includes a phase shifter for a base station antenna and a base station antenna.

摘要： Printed circuit boards suitable for base station antennas have a first through hole for receiving a conductor of an electrical connector and a first conductive trace for electrical connection with the conductor to transmit signals. The first conductive trace is provided on a first side of the printed circuit board and the electrical connector is located on the same side of the first conductive trace when mounted on the printed circuit board. The conductor is electrically connected to the first conductive trace via a bypass provided on a second side of the printed circuit board, opposite to the first side. The printed circuit board can be provided for a base station antenna that includes a calibration board including the printed circuit board. The printed circuit board can facilitate the good positioning of the electrical connector thereon, the good electrical performances, or can avoid a possible short circuit.
