A low insertion loss (IL) analogue predistorter using non-linear composite right-left-handed transmission line (CRLHTL) is presented. The proposed predistorter consists of two symmetrical CRLHTL unit cells. In the experiment, this predistorter can achieve about 2.2 dB gain expansion and 17° phase shift during 4.4-4.5 GHz with only 4.3 dB IL. A C-band 40 W solid-state power amplifier observes 8.1 dB enhancement in the intermodulation at -6 dB output power backoff when linearised by the proposed predistorter. [ABSTRACT FROM AUTHOR]
