Abstract
This paper discusses the state of the art in achieving wideband (>1 GHz) linearization of TWTAs. Multioctave bandwidth linearization has been achieved at frequencies from L- to Ka-band. The trades between using a single predistortion linearizer and multiband linearizers are discussed. The effect of harmonics (both even and odd-order-distortion products) and their correction for applications that cover more than an octave are considered.
