  • RF amplification device and RF transmitter comprising such a device
    Patent number: 10727883
    Abstract: Operating in a low frequency band and a high frequency band, the device includes at least a first amplification module capable of operating in the high band, the amplification of which is modulated according to a tracking of the envelope of the input signal of the device, capable of being linked at the output to an antenna adapted to the high band; a second amplification module capable of operating in the low band and of performing the envelope tracking; a switch switching the output of the second amplification module to an antenna adapted to the low band, when the amplification device is operating in the low band; to the first amplification module to control the drain voltage of the first module according to the envelope tracking, when the amplification device is operating in the high band.
