Polar and linear amplifier system |
摘要 |
An amplifier system is provided that switches between operation in a polar mode and a linear mode based on a characteristic of an input signal relative to a threshold level. The system operates as a polar amplifier in the polar mode, and as a linear amplifier in the linear mode. A mode selector controls whether polar components of the input signal are sent to a power amplifier or whether a composite signal is amplified.
