A new linear amplifier using low-frequency second-order intermodulation component feedforwarding
Youngoo Yang,Bumman Kim +1 more
TL;DR: In this article, a new linearization method by feedforwarding low-frequency second intermodulation component (f/sub 2/- f/sub 1/) improves linearity significantly.
Proceedings ArticleDOI
SDR transmitter based on LINC amplifier with bias control
TL;DR: The results, compared with conventional cases, clearly show the suitability of the new LINC transmitter for SDR application.
Journal ArticleDOI
