    • An apparatus includes a first amplification stage configured to amplify a first carrier signal and a second amplification stage configured to amplify a second carrier signal. The first amplification stage is direct-current (DC) coupled to the second amplification stage. First circuitry is coupled to the first amplification stage and configured to control a first gain of the first amplification stage. The first circuitry includes a first gain control transistor configured to selectively divert a first bleed current from a first output of the first amplification stage. Second circuitry is coupled to the second amplification stage and configured to control a second gain of the second amplification stage independently of the first gain. The second circuitry includes a second gain control transistor configured to selectively divert a second bleed current from a second output of the second amplification stage.
    • 一种装置包括被配置为放大第一载波信号的第一放大级和被配置为放大第二载波信号的第二放大级。 第一放大级是耦合到第二放大级的直流(DC)。 第一电路耦合到第一放大级并且被配置为控制第一放大级的第一增益。 第一电路包括第一增益控制晶体管,其被配置为选择性地转移来自第一放大级的第一输出的第一泄放电流。 第二电路耦合到第二放大级并且被配置为独立于第一增益来控制第二放大级的第二增益。 第二电路包括第二增益控制晶体管,其被配置为选择性地转移来自第二放大级的第二输出的第二放电电流。
