摘要：
An amplifier structure (200) includes a main amplifier loop (203) for efficiently amplifying an input signal at a power amplifier (228) coupled to a load susceptible to impedance variations. The amplifier loop (200) further includes an auxiliary loop (201) coupled to the main loop (201) for simultaneously preventing the power amplifier (228) from operating inefficiently or causing off-channel interference.
