description: Through the use of increasingly complex technologies (high-order modulation technology, OFDM, etc.), the performance of wireless communications has been significantly improved, but the resulting signal peak-to-average ratio problem has become increasingly serious. Traditional RF power amplifiers are increasingly unable to meet the requirements of high efficiency and high linearity. Chireix outphasing power amplifier is regarded as one of the promising technologies that can provide high linearity and high efficiency at the same time, but the implementation of its key part - the signal component separator is complicated. This article studies a purely digital implementation of a signal component separator, which uses the CORDIC algorithm and lookup table in FPGA to implement and cooperates with a high-speed DAC to convert the processed signal into an analog signal for subsequent amplification. The prototype of the signal generator is built based on Zynq 7010 and AD9744, and the actual measurement results are consistent with the simulation. The ideal EVM of the 4096-QAM signal processed by this design is -66.97dB (0.045%), which meets the requirements of the IEEE 802.11be standard of less than -38dB (1.26%).
