  • Filter apparatus, multiplex device and associated method
    Patent number: 9337947
    Abstract: It is presented a filter apparatus comprising: a first frequency shifter arranged to accept an input signal of the apparatus; a first filter; a second frequency shifter; a second filter; and a third frequency shifter, the output of which is connected to the output of the apparatus. The first frequency shifter, the first filter, the second frequency shifter, the second filter and the third frequency shifter are serially connected; and each one of the first frequency shifter, second frequency shifter and third frequency shifter has separate shift input signals, respectively. A corresponding radio base station assembly and method are also presented.

  • Antenna control system
    Patent number: 7505010
    Abstract: An antenna control system for setting the tilt angle of a main lobe of an antenna, in particular of an antenna constituting part of a base station in a mobile cellular communication system, said antenna comprising a plurality of antenna elements and phase shifting means for varying the phase of at least one signal being fed to said antenna elements, wherein adjustment of said phase of said signal is achieved by actuating an operating element, and wherein actuation of said operating element is achieved by operating an operating element actuator. The operating element actuator is coupled to the operating element of the phase shifting means by means of a force field coupling.
