A LINC transmitter provides linear amplification while employing two nonlinear high-efficiency power amplifiers. This work proposes a LINC architecture where the two constant-envelope components of the signal are separated in the baseband analog domain. The signal component separator can achieve a power consumption which is significantly lower than conventional digital implementations. A signal component separator for 64-QAM 802.11a/g Wireless LANs is implemented in a 0.25- mum CMOS process, the circuit occupies less than 0.1 and consumes 45 mW from the 2.5-V supply. The measured EVM, ACPR, and alternate-ACPR of the recombined signal components are , and , respectively.
