    摘要： The disclosed invention relates to a MIMO (multiple input, multiple output) wideband transceiver. In some cases, the MIMO wideband transceiver comprises a signal processor that outputs or receives a plurality of distinguishable data streams. A first data stream is provided to a first antenna port connected to a plurality of wideband antennas, while a second data stream is provided to a second antenna port connected to a wideband antenna. A spatial filter element configured to assign antenna weights to the plurality of wideband antennas, which cause the wideband antennas to operate in a manner that attenuates wireless signals, at a frequency range at which the wideband transmit wideband radiate, in the direction of the wideband antenna without attenuating the wireless signals in other directions. By attenuating signals extending between the plurality of wideband antennas and the wideband antenna, wideband decoupling between first and second antenna ports is achieved.

    摘要： A self-calibration circuit and associated method for testing an RF device includes the RF device to be tested having transmit and receive sections, and a built-in self test (BIST) circuit coupled to the transmit and receive sections of the RF device on the same chip. The self-calibration circuit is configured to calibrate the receive section of the RF device in a receive test mode, and calibrate the transmit section of the RF device in a subsequent transmit test mode using the calibrated receive section to measure a transmit output signal from the transmit section and to provide calibration data therefrom used in the transmit section calibration. The self-calibration circuit may include a duplex filter coupled between the transmit and receive sections and the BIST circuit, and a multiplexor coupled between the RF device, and the BIST circuit, configured to select one or more of a plurality of RF devices to be tested.

    摘要： The disclosed invention relates to a transceiver system having one or more receive antennas that receive a first radio frequency (RF) signal and a plurality of transmit antennas that wirelessly transmit a second RF signal. A local channel determination unit provides data corresponding to the environment of local communication channels (i.e., the communication channels between the transmit antennas and the receive antennas) to a beamforming element, which enables beamforming functionality within the transmit and/or receive antennas (e.g., by using analog or digital weights to vary the radiation pattern generated by the transmit antennas) so as to attenuate RF signals extending between the transmit antennas and the receive antennas. By attenuating signals extending between the transmit and the receive antennas, a high degree of isolation is achieved between transmission and reception paths.

    摘要： The present disclosure relates to a wireless communication system configured to transforming the radiating mechanism of the antenna system in such a way to support different operating modes depending on the needs. In some examples, the wireless communication system comprises an antenna structure connected to a signal process unit. The antenna structure comprises a radiating mechanism configured to transmit or receive electromagnetic radiation. A switchable operating mode element is configured to receive a signal and to dynamically vary a quality factor of the radiating element by selectively routing the signal along one of a plurality of signal paths, which respectively provide different antenna parameters to the radiating mechanism, based upon a current operating mode of the wireless communication system. By dynamically varying a quality factor of the radiating element, the wireless communication system can effectively support different operating modes.

    摘要： The disclosed invention relates to an antenna configuration that is configured to tune the frequency of transmission without using filters. The antenna configuration comprises a tunable multi-feed antenna configured to wirelessly transmit electromagnetic radiation. A signal generator is configured to generate a plurality of signals that collectively correspond to a signal to be transmitted. The plurality of signals have a phase shift or amplitude difference therebetween. The plurality of signals are provided to a plurality of antenna feeds connected to different spatial locations of the tunable multi-feed antenna. The values of the phase shift and/or amplitude difference define an antenna reflection coefficient that controls the frequency characteristics that the tunable multi-feed antenna operates at, such that by varying the phase shift and or amplitude difference, the frequency characteristics can be selectively adjusted.
