Abstract:
1. A multiple branch transmitter, comprising: a. a baseband processing block for conditioning an input baseband signal; b. a signal up-conversion block, having an input and an output, said input of said signal up-conversion block being connected to outputs of said baseband processing block, said signal up-conversion block being adapted to generate analog RF signals based on the sub-signals obtained from the baseband processing block; c. an RF power amplification block having an input and an output, said input of said RF power amplification block being connected to said output of said signal up-conversion block, said RF power amplification block to amplify the analog RF signals present at its inputs; d. an RF combining network having an input connected to said output of said RF power amplification block, and an output that combines the amplified analog RF signals obtained from the RF power amplification block, and wherein the baseband processing block continuously monitors a power envelope of the input signal, and based on the instantaneously monitored power envelope dynamically varying a signal splitting ratio to split the input signal between a plurality of baseband output signals.
