  • Patent number: 11757184
    Abstract: Examples disclosed herein relate to a switched coupled inductance phase shift mechanism for beamsteering an antenna array and applied in a radar system or a communication system. The phase shift mechanism includes a variable inductor element configured to toggle between a first inductance state and a second inductance state in response to a first control bit value, and a plurality of variable capacitor elements coupled to the variable inductor element and configured to toggle between a first capacitance state and a second capacitance state in response to a second control bit value. The variable inductor element and the variable capacitor elements collectively produce a first phase shift using the first inductance and capacitance states, and collectively produce a second phase shift using the second inductance and capacitance states, where a target phase shift is produced from a difference between the first and second phase shifts.

  • Publication number: 20220416726
    Abstract: Adaptive bias networks include small transistors connected to adjust gate bias voltage of one or more transistors of an amplifier or amplifier stage, or in a main or auxiliary path of a compound amplifier such as a Doherty amplifier. The small transistors are sized to avoid additional loading of the input. The adaptive bias circuits of preferred embodiments adjust the gate bias to produce a boost in gate bias voltage of an nFET transistor when the input power is in an upper portion of the amplifier or amplifier stage's input power range, thereby increasing the gain, and reduce gate bias voltage of a pFET transistor in the upper portion of the amplifier's input power range, thereby also increasing the gain. The adaptive bias networks can be implemented with varactors to vary DC voltage across the varactor to change its capacitance and compensate changing input capacitance of the amplifier input FET.

  • Publication number: 20210389447
    Abstract: In accordance with various implementations, a radar system comprising a non-line of sight (NLOS) module to enhance operation of the radar system is provided. In various embodiments, the NLOS module is a radar repeater module with phase shifters to generate an indication of an object detected in a NLOS area. In various embodiments, the NLOS module includes a reflector structure configured to reflect or redirect radar signals from a train on the tracks into a NLOS area. The NLOS module can include a receive antenna, a transmit antenna configured to transmit one or more received radar signals into a NLOS area, and a phase shifting module for applying a phase shift to a radar signal reflected from an object in the NLOS area that is outside an operational range of the radar unit.

  • Publication number: 20210376464
    Abstract: A radar system for interacting with navigation targets is provided. The radar system is configured to interact with navigation targets (target devices) that shift the phase of a received radar transmission to generate a phase shifted response signal. Phase shifters (e.g., silicon germanium phase shifters) are designed to assign specific frequency responses from one or more navigation modules to identify target locations. The radar module transmits at a modulated signal at first frequency, each navigation target receives the radar transmission, phase shifts the signal and returns the phase shifted signal. Where two or more navigation targets are used, each will apply a different phase shift to the received radar transmission, wherein the frequency identifies the navigation target devices. In a radar system, the modulated transmission signal is compared to the returned phase shifted signal to determine a frequency difference between the two signals.
