  • Patent number: 10931033
    Abstract: A multi-polarization millimeter wave (mmWave) transmitter/receiver (TX/RX) architecture with shared power amplifiers (PAs) is provided. This architecture provides a transceiver which uses shared PAs to reduce the number of TX and PA stages required for multi-polarization transmission in mmWave radio frequency (RF) devices. Embodiments provide an array of switching channels which selectively connect a shared TX and shared PA to two or more antennas in antenna arrays having different polarizations (e.g., a dipole antenna array and a patch antenna array). This approach provides a dual polarization or multi-polarization mmWave transceiver having a reduced number of components which results in a smaller size, improved power efficiency, and improved power heat dissipation.

  • Patent number: 10911087
    Abstract: A receiver and a receiving method of the receiver such that monolithic integration of multiple receiving channels can be implemented. The receiver includes a zero intermediate frequency channel, performing in-phase/quadrature (IQ) down conversion on a radio frequency signal at a first frequency band using a frequency division or frequency multiplication signal of a first signal, and a superheterodyne channel, performing down conversion on a radio frequency signal at a second frequency band using the frequency division or frequency multiplication signal of the first signal, where the first frequency band is different from the second frequency band. The zero intermediate frequency channel and the superheterodyne channel use a same oscillation signal or a same frequency division or frequency multiplication signal of the oscillation signal, thereby monolithic integration of multiple receiving channels can be implemented.

  • Patent number: 10887026
    Abstract: Technologies directed to antenna disconnection detection of distributed radio frequency (RF) ports in a wireless network are described. One method receives data from the wireless devices and generates an RSSI matrix including multiple elements, each storing a receive signal strength indicator (RSSI) value indicative of a signal strength of a wireless link between a transmitter-receiver pair. The method identifies a characteristic pattern in the RSSI matrix. The characteristic pattern includes i) two or more RSSI values in a same row being less than the threshold value and ii) two or more RSSI values in a same column being less than the threshold value. The method stores an indication that an antenna is disconnected from an RF port and sends a command to the second wireless device that causes the second wireless device to disable a radio that is coupled to the RF port.

  • Patent number: 10873352
    Abstract: A radio-frequency module (20) includes a module substrate (50) and a filter (21). The filter (21) has a sensitive GND electrode and a non-sensitive GND electrode that are connected to an external-connection ground terminal of the module substrate (50), and parallel-arm resonators. An inductance component generated by the sensitive GND electrode shifts, by a first shift amount, an attenuation pole that corresponds to a parallel-arm resonator and that is formed near a pass band. An inductance component generated by the non-sensitive GND electrode shifts, by a second shift amount, an attenuation pole that corresponds to a parallel-arm resonator and that is formed near the pass band. The first shift amount is larger than the second shift amount, and the distance between the sensitive GND electrode and the external-connection ground terminal is smaller than the distance between the non-sensitive GND electrode and the external-connection ground terminal.

  • Patent number: 10833900
    Abstract: A receiver signal is sampled at a sampling rate equivalent to a chip rate at which chips of a known signal are timed. The resulting receiver signal samples are segmented into receiver signal segments, which are filtered by respective matched filters that are matched to known signal segments segmented from the known signal. Indexes are assigned to elements of the resulting filter response sequences to define an array thereof. Frequency transforms are computed of elements of the filter response sequences in respective columns of the array. Indexes are assigned to elements of the resulting frequency response sequences to define another array thereof. Channel effects imparted on a radio signal are jointly estimated from characteristics of the other array at which at least one local maximum is located.

  • Patent number: 10790889
    Abstract: Hybrid beamforming may be configured for wireless communication systems (e.g., multiple-input multiple output (MIMO) and/or massive-MIMO). The implementation(s) may determine a number of radio frequency (RF) chains for realizing a fully digital precoder (FDP) in a structure (e.g., a hybrid analog/digital precoder). The number of RF chains may be less than a number of transmitter antennas. A transmit vector signal may be determined based on a digital precoder and an input symbol vector. An analog precoder and/or a baseband signal may be determined based on the determined transmit vector signal. The number of RF chains may be determined based on the determined baseband signal. The baseband signal may be fed to the determined number of RF chains. The analog precoder may determine a beamforming signal based on an output of the determined number of RF chains. The analog precoder may transmit the beamforming signal using the number of transmitter antennas.
