Radio frequency transmitter
Abstract:
A radio frequency transmitter device, constituted for transmitting a radio frequency signal in a frequency band comprising at least one transmit subband and at least one receive subband, comprises: a transmit chain for processing a transmit signal associated with the at least one transmit subband; a power amplifier for amplifying the transmit signal; an output port for transmitting the amplified transmit signal; a processing unit for calculating, from the transmit signal associated with the at least one transmit subband, a correction signal in the at least one receive subband making use of a power amplifier model modelling the behavior of the power amplifier; and a coupler for adding the correction signal to the amplified transmit signal for cancelling intermodulation products in the amplified transmit signal produced by the power amplifier.
