  • Wireless communications system having variable gain mixer
    Patent number: 6917788
    Abstract: A wireless communications transceiver system and a variable gain mixer used in the wireless communications transceiver system. The differential mixed output signal of the variable gain mixer is a constant current signal. The gain of the mixer is set by selectively connecting into the input section circuit of the mixer a degeneration impedance. By maintaining the current of the mixed output signal constant, the linearity of the variable gain mixer is maintained constant and there are no changes in harmonic rejection.
    Type: Grant
