Abstract
A multipath power amplifier device, configured to operate in a high power mode and a low power mode, includes a high power path, a low power path and an output switch. The high power path includes a high power mode (HPM) amplifying circuit for amplifying an input signal in the high power mode. The low power path includes a low power mode (LPM) amplifying circuit for amplifying the input signal in the low power mode. The output switch is configured to isolate the low power path from the high power path in the high power mode.
