Polar and linear amplifier system |
| 摘要 |
<p>The system has a main power amplifier (22) that is operative to amplify an input signal. A mode selector (16) controls the operation of the power amplifier between a polar mode and a linear mode, based on a characteristic of the input signal relative to a threshold level. The selector controls whether polar components of the input signal are sent to the amplifier or whether a composite signal is amplified.</p> |
