Sv. Melikhov et Gn. Yakushevich, A BROAD-BAND MIXER WITH INCREASED DYNAMIC-RANGE FOR A FREQUENCY-SYNTHESIZER, Instruments and experimental techniques, 41(1), 1998, pp. 79-80
An ultrahigh-frequency broadband mixer for frequency synthesizers and
panorama receivers with a decreased (down to -36 dB) relative level of
combination fourth-order frequency components is described. This decr
ease is achieved by using an external bias voltage and stabilizing the
average current component in diodes.
