  • Patent number: 11588239
    Abstract: An array of antennae includes a monobit transmitter to insert dither into a transmit signal to form a dithered transmit signal. Monobit receivers process received signals that are combined with the dithered transmit signal to form composite received signals. Digital down converters process the composite received signals to form down converted received signals. A beamformer circuit processes the down converted received signals to form recovered signals.

  • Patent number: 11469722
    Abstract: Systems and apparatuses are disclosed that include a modular power amplifier having a power amplifier subsystem with a first 90 degree hybrid block configured to receive an RF signal and output a split RF signal with components having a 90 degree phase shift, a second 90 degree hybrid block configured to receive and combine the split RF signal by removing the 90 degree phase shift, a high-power amplifier configured to amplify at least one of the components of the split RF signal. The modular power amplifier also includes a power distribution module configured to regulate an amount of power input to the high-power amplifier and a power sequencer configured to control the timing of power delivery by the power distribution module.

  • Patent number: 6963442
    Abstract: A frequency synthesizer for generating a multiple tone lightwave signal that can be converted into an RF carrier or local oscillator signal. The frequency synthesizer comprises a multiple mode master laser, two slave lasers injection-locked to the master laser, an optical coupler coupling the optical outputs of the two slave lasers, which produces an optical heterodyne output. The frequency synthesizer further comprises a homodyne phase-lock loop providing feedback control over one of the slave lasers and a heterodyne phase-lock loop providing feedback control over the other slave laser. A local oscillator selector is used to select the optical mode to which one of the slave lasers is locked, thus providing selection of the frequencies of the heterodyne output.

  • Patent number: 5422605
    Abstract: A low phase noise oscillator 10 having a balanced feedback transformer 24 and a push-pull resonant circuit 12 for generating an oscillation excitation signal. The resonant circuit 12 is loaded by an output buffer 20 connected between first and second feedback terminals 16 and 18. The feedback transformer 24 provides first and second feedback paths of opposite phase polarity which link the resonant circuit 12 with the first and second feedback terminals 16 and 18.
