摘要： A method includes pointing a receive beam of a retro-directive antenna array attracted to a jammer circuit instead of a remote transmitter away from the jammer circuit toward the remote transmitter by a first angle based on coarse manual means therefor implemented in electronic circuitry associated with the retro-directive antenna array. The electronic circuitry includes a number of mixers, each of which is configured to mix a Local Oscillator (LO) signal generated from a Voltage Controlled Oscillator (VCO) with a signal received at an antenna element of the retro-directive antenna array. The method also includes automatically fine pointing the receive beam toward the remote transmitter by a second angle following the coarse pointing thereof by the first angle such that the receive beam exactly points to, and tracks, the remote transmitter. The automatic fine pointing is effected through a secondary automatic servo loop implemented in the electronic circuitry.

摘要： A method includes separating phase of Local Oscillator (LO) signals generated by individual Voltage Controlled Oscillators (VCOs) of a coupled VCO array through varying voltage levels of voltage control inputs thereto. The method also includes frequency multiplying an output of each individual VCO of the coupled VCO array to increase a range of phase differences between the phase separated LO signals generated by the individual VCOs. Further, the method includes mixing the frequency multiplied outputs of the individual VCOs with signals from antenna elements of an antenna array to introduce differential phase shifts in signal paths coupled to the antenna elements during performing beamforming with the antenna array.

摘要： A method includes receiving a remote transmitter signal at an antenna array including a number of antenna elements, mixing the received signal with in-phase and quadrature-phase Local Oscillator (LO) signals from Voltage Controlled Oscillators (VCOs) of a coupled VCO array, and configuring each Phase Locked Loop (PLL) of a number of PLLs to receive an in-phase output of the mixing corresponding to a VCO and a quadrature-phase output of the mixing corresponding to another VCO adjacent to the VCO as inputs thereto. The method also includes feeding back an output of the each PLL to the VCO, driving the in-phase and the quadrature-phase outputs of the mixing from a transmit modulator, and transmitting, in a direction of the remote transmitter, an antenna array signal based on the driving. Further, the method includes sensing a servoed state related to LO phase relationships and holding thereof during the transmission of the signal.

摘要： A method includes configuring a battery and a voltage regulator configured to regulate an output voltage of the battery to supply power to a memory of an electronic circuit also comprising non-memory circuitry. The method also includes switching the supply of power between the battery and the voltage regulator such that: the memory is powered from the battery when the non-memory circuitry is inactive, the memory is powered from a combination of voltage from the battery and the voltage regulator when the memory is about to communicate with the non-memory circuitry during a transition of the non-memory circuitry into an active state thereof, and the memory and the non-memory circuitry are powered from the voltage regulator during the active state of the non-memory circuitry. Thus, minimal current is drawn from the battery while a state of the memory of the electronic circuit is preserved.
