1. radio frequency receiver that is used to be coupled to antenna comprises:

  • Down-conversion mixer;

    Amplifier, first output of importing that has the input of being coupled to described antenna and be coupled to described frequency mixer is used for providing the frequency signal that is received to described frequency mixer;

    AndVoltage controlled oscillator, output with second input of being coupled to described frequency mixer, be used for providing mixed frequency signal to described frequency mixer, the assembly of wherein said amplifier and described voltage controlled oscillator is configured to show substantially the same resonant circuit topology, and is implemented in the same integrated circuit with other assembly of the front end of described receiver.
