Apparatus and method for driving a sectored antenna
An apparatus for driving a sectored or multi beam antenna configuration and corresponding method of level loading amplifiers is suitable for use in a transmitter. The apparatus includes a plurality of Fourier Transform Matrix (FTM) devices 501, each FTM device having a plurality of outputs 513 and a plurality of inputs 511; where the plurality of outputs of an FTM device 503 include a first output A1 and a second output B2 arranged to be coupled, respectively to a first antenna array 403 and a second antenna array 405 and these antenna arrays are included in a plurality of antenna arrays collectively comprising the antenna configuration where the first antenna array and the second antenna array corresponding to different sectors and beams, and a plurality of amplifiers 517, 519, 521, 523 corresponding to each of the FTM devices, where one of the plurality of amplifiers coupled to and driving each of the plurality of inputs.
