摘要:
A mobile communication device comprises a plurality of spatially and/or polar diverse antenna configurations. Signals received by each of the plurality of antenna configurations are combined in a combiner and passed to a rake receiver that can be configured to combine the signals received by each of the plurality of antenna configurations for further processing. The mobile communication device can comprises a signal adjusting network that can be configured to adjust the phase and/or magnitude of signals being received by one of the antennas.
摘要:
An apparatus and method are presented for combining electrical signals. The apparatus includes a phase-shift distributed element with an input to accept a first signal and an output to supply the first signal with a phase-shift; and a filter with a first signal port connected to the phase-shift element output, a second signal port to accept a second signal, and a third signal port to supply combined and filtered first and second signals. The phase-shift element has a signal path with a predetermined length and the phase-shift element output supplies the first signal with a phase angle shift responsive to the length of the signal path. In one example, the phase-shift element is formed from monoblock and coaxial elements, either singly or in combination, and is a tank circuit resonator in the filter.
