1. high-frequency amplifier comprises:

  • An amplifying device is used to amplify the multi-carrier signal that carrier wave produced by a plurality of separate modulation of combination;

    WithA filter is connected with the output of described amplifying device, has;

    A rejection band is positioned within the frequency band range that described multi-carrier signal occupies,Such transfer characteristic is convenient to the level of noise is suppressed under the predetermined upper limit, and described noise is to produce with the modulation product that modulation product between the multi-carrier signal and frequency equal frequency axis upper frequency difference Δ

    f, as the composition product between the described carrier wave andA passband comprises described difference on the frequency Δ

    f in its scope.
