Abstract:
An envelope tracking (ET) circuit is provided. In the ET circuit, a number of amplifier circuits are configured to amplify a radio frequency (RF) signal simultaneously to generate multiple RF transmit signals for transmission in a formed RF beam. The RF signal is pre-modulated into respective phase and amplitude terms such that the multiple RF transmit signals can be linearly combined at a receiver(s). A signal processing circuit is configured to determine a combined distortion term in the multiple RF transmit signals. Accordingly, the signal processing circuit pre-distorts the RF signal with a distortion correction term to offset the combined distortion term in the RF transmit signals. By introducing the distortion correction term in the RF signal, it is possible to restore linear coherency among the RF transmit signals without compromising efficiency and/or increasing heat dissipation of the amplifier array(s).

Claim (Index 8):
The ET circuit of  claim 7  wherein the signal processing circuit further comprises a plurality of signal digital-to-analog converter (DAC) pairs configured to convert the plurality of modulated digital signals into the plurality of pre-processed RF signals modulated in the plurality of phase and amplitude terms.
