  • DUAL ARCHITECTURE RADAR
    Publication number: 20260110797
    Abstract: A system may include a first signal generator communicatively couplable to a first antenna via a switch and configured to generate a carrier signal for a pulsed radar signal. A system may include a second signal generator communicatively couplable to the first antenna via the switch and coupled to an image reject mixer, the second signal generator configured to: transmit, when the first signal generator is communicatively coupled to the first antenna, a local oscillator continuous wave signal to the image reject mixer, and transmit, when the second signal generator is communicatively coupled to the first antenna 1) a first frequency modulated continuous wave signal via the first antenna, and 2) a second frequency modulated continuous wave signal to the image reject mixer, wherein the third continuous wave is mixed with a reflection of the first frequency modulated continuous wave signal received by the second antenna.

  • Tri-fin TCAS antenna
    Patent number: 9019161
    Abstract: A low drag TCAS antenna includes a plurality of broadband antenna elements in a housing having at least three fins. L band radios in the aircraft may utilize the broadband antenna elements, thereby reducing power consumption, cost and aerodynamic inefficiency due to a plurality of antennas protruding from the aircraft.

  • Adaptive DME transmitter architecture
    Patent number: 8744800
    Abstract: A distance measuring, device including a lookup table storing values to calibrate a Class AB amplifier to produce a pulse pair with the desired characteristics. The distance measuring device analyzes the characteristics of the output signal and recursively adapts the values stored in a lookup table to force the output the power amplifier to meet the required performance characteristics.

  • Balanced distortion reduction circuit
    Patent number: 6734726
    Abstract: A method and apparatus for utilizing the distortion generated within a portion of a balanced amplifier to cancel the distortion generated within the whole balanced amplifier. Samples of the signal and distortion from part of the balanced amplifier are combined with a reference signal such that the two signals destructively combine leaving the distortion from the sampled part of the balanced amplifier. The gain and phase of the distortion is then adjusted so that when it is coupled into the input of the other part of the balanced amplifier the distortion generated by both parts of the balanced amplifier are cancelled.
