Abstract—A LINC transmitter provides linear amplification
while employing two nonlinear high-efficiency power amplifiers.
This work proposes a LINC architecture where the two con-
stant-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 sepa
