Abstract

Certain aspects of the present disclosure provide a switch architecture for switching between a low power amplifier and a high power amplifier. One example amplification system includes a high power amplifier and a low power amplifier. The amplification system further includes a first switch coupled between the high power amplifier and an output. The amplification system further includes a second switch coupled between the output and a reference potential. The second switch is further coupled between the low power amplifier and the output and configured to selectively couple the low power amplifier to the output. The amplification system further includes a third switch coupled between the low power amplifier and the second switch.
