In some embodiments, the GNSS receiver includes a tuner to tune the resonant frequency of the second linear polarization antenna. In some embodiments, the GNSS receiver includes a switch or a filter to connect or disconnect the second linear polarization antenna from the hybrid coupler to implement a circular polarization antenna or a linear polarization ante.

摘要： Systems, methods, and apparatus for communication over to serial bus in accordance with an I3C protocol are described. A method performed at a master device includes causing a line driver to enter a high-impedance mode of operation, and receiving data from the serial bus. When a data line of the serial bus is in a high voltage state while a last bit of a data byte is being transmitted, the line may be configured for an open-drain mode of operation, and transmitting a START condition on the serial bus while the last bit of the data byte is being transmitted. When a plurality of data bytes is sequentially transmitted with last bits that cause a low voltage state, the line may be configured for an open-drain mode of operation, and transmitting a START condition on the serial bus after the last bit of the data byte is being transmitted

摘要： A reconfigurable RF receive diplexer, which includes a first hybrid RF coupler, a second hybrid RF coupler, and reconfigurable RF filter circuitry, is disclosed. The reconfigurable RF receive diplexer receives a first adjunct RF antenna receive signal via a first isolation port to provide a first adjunct RF receive signal via a second main port. The reconfigurable RF receive diplexer further receives a first RF transmit signal via a first main port to provide a first RF antenna transmit signal via the first isolation port. The reconfigurable RF receive diplexer operates in each of a group of operating modes, such that during a first operating mode, a carrier frequency of the first adjunct RF antenna receive signal is within a first RF communications band; and during a second operating mode, a carrier frequency of the first adjunct RF antenna receive signal is within a second RF communications band.

摘要： Antenna units, antenna systems and polarizing systems provide polarization diversity to leaky-wave antennas. An antenna unit comprises a rat-race coupler having a summation port, a difference port and two output ports. Each one of a pair of composite right/left-handed (CRLH) leaky-wave antennas (LWA) is connected at one end to a respective one of the output ports of the rat-race coupler. An inductive stub is implemented between the CRLH LWAs for connecting the CRLH LWAs to a grounded via. Various polarizations are obtained by injecting a radio-frequency (RF) signal in the summation or difference port of the rat-race coupler, or in both ports. System variants include various devices and assemblies for injecting RF signals in the antenna unit. One such variant includes a polarizing system having a switched matrix for directing a signal according to various intended polarizations.
