Abstract:
The present disclosure relates to a switchable transmission mechanism for a base station antenna. The switchable transmission mechanism includes a plurality of axially drivable members, each of which is mounted on a corresponding one of a plurality of transmission rods arranged in parallel and is configured to be connected with a corresponding one of a plurality of phase shifters in the base station antenna; a transmission unit including a first gear assembly and a second gear assembly transmissibly connected to the first gear assembly, where the second gear assembly is engageable with or dis-engageable from any one of the transmission rods via a rod adapter that is movable between an engaged position and a disengaged position along an axial direction; and a switch unit configured to move the second gear assembly along a lateral direction perpendicular to the axial direction when the second gear assembly is disengaged from the transmission rod, so that the switchable transmission mechanism can selectively drive any one of the transmission rods.
Abstract:
The present invention relates to a transmission device for a phase shifter and an actuator device for a phase shifter. The transmission device includes a support, a lead screw nut mechanism and an automatic locking device. The automatic locking device includes a shaft connector rotatably supported on the support and configured to be in transmission connection with a driven connector of a driving device; a locking connector which is in transmission connection with the shaft connector, is in transmission connection with the lead screw, has a locking element and is movable relative to the shaft connector and the lead screw; and a locking spring. When the driven connector is decoupled to the shaft connector, the locking spring biases the locking connector in a first position, in which the locking element engages a counter-locking element on the support. When the driven connector is decoupled to the shaft connector, the locking connector is moved by the driven connector to a second position, in which the locking element disengages the counter-locking element on the support. Calibration of the phase shifter may be saved when the driving device is replaced or repaired.
Abstract:
An assembly for adjusting an electrically regulated antenna includes a control device, a motor and a cable. The control device is connected with the motor via the cable, and a shielding material in the assembly for adjusting the electrically regulated antenna comprises alum-glass cloth tape. The shielding material composed of the alum-glass cloth tape is used for improving the electromagnetic shielding effect, particularly the passive intermodulation effect, of an electrically regulated antenna system. The invention further relates to a method for manufacturing the assembly for adjusting the electrically regulated antenna.

Abstract:
A test fixture for testing performance of a trimmed cable and/or antenna components. The test fixture may be connected without the use of solder allowing for accurate testing or tuning of one or more the antenna components.
Abstract:
The present disclosure relates to a connector assembly and a base station antenna comprising such connector assembly. The connector assembly comprises a connector (1), where the connector has a port (11). The connector assembly further comprises a guide ring (2), where the guide ring is installed in front of the port of the connector and is radially and elastically supported. The guide ring has an inner surface (21) that tapers towards the port of the connector on part of the axial length, and is used to guide the port of the matching connector in the port of the connector. The connector assembly allows increased deviation when matching connectors are mated.
