  • 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.
