A 6 to 16 GHz Linearized GaN Power Amplifier

This paper discusses a predistortion linearizer developed for use with multi-octave high power GaN amplifiers. This linearizer was produced as a GaN MMIC and displays useful characteristics over a frequency range from less than 4 GHz to greater than 20 GHz. It achieved more than an 8 dB improvement...

Zusammenfassung:This paper discusses a predistortion linearizer developed for use with multi-octave high power GaN amplifiers. This linearizer was produced as a GaN MMIC and displays useful characteristics over a frequency range from less than 4 GHz to greater than 20 GHz. It achieved more than an 8 dB improvement in C/I across the frequency range from 6 to 16 GHz with a 10 watt broadband MMIC GaN power amplifier. The authors believe this linearizer to be the first linearizer produced in GaN and also the widest band linearizer reported to date
