  • Waveguide excited enhancement and inherent rejection of interference in a subharmonic mixer
    Patent number: 4955079
    Abstract: A subharmonic mixer is shown to comprise two pairs of matched antiparallel GaAs diodes disposed on a dielectric slab and operative with microstrip circuitry. By suppressing the fundamental mixing products, mixing the radio frequency signal with the second harmonic of a local oscillator (LO) signal and using relative phase differences of the LO signals in the two pairs of diodes, undesirable effects from spurious signals are minimized.
    Type: Grant
    Filed: September 29, 1989
    Date of Patent: September 4, 1990
    Assignee: Raytheon Company
    Inventors: William R. Connerney, Mark E. Raposo, Winslow G. Round, Raymond T. Pavio
  • Waveguide feed network for antenna array
    Patent number: 4952894
    Abstract: An improved corporate feed network for distributing radio frequency energy to elements of an antenna array is shown. The corporate feed network comprises an improved feed coupler, including a quadrature hybrid junction for dividing radio frequency (R.F.) energy from an input port into the two waveguides and a plurality of secondary waveguides disposed orthogonally to the first and second waveguides, each of the secondary waveguides having narrow walls common to broad walls of the first and second waveguides with apertures formed through common sections of such walls, the common sections being offset to impart directional characteristics to the corporate feed network.

  • Radio frequency mixer
    Patent number: 4654887
    Abstract: A wideband enhancement sum mixer is shown to comprise a pair of matched GaAs diodes operative with a printed circuit wherein a portion of at least the sum signal, i.e., the sum of a radio frequency signal and a local oscillator signal, is caused to be mixed with the second harmonic of the local oscillator signal to produce an intermediate frequency signal in phase with the intermediate frequency signal resulting from mixing of the radio frequency signal and the local oscillator signal.

  • Single sideband generator with leakage signal cancellation
    Patent number: 4410863
    Abstract: Suppressing the L.O. leakage signal in the second converter section of a gle sideband generator by utilization of a generator bypass circuit which supplies a signal at the generator output which in turn cancels the leakage L.O. signal.
