This article presents a method for estimating a linear time-varying approximation of a general class of nonlinear time-varying (NLTV) systems. It starts from noisy measurements of the response of the ...

This paper presents a broadband high-efficiency and good-linearity power amplifier for L-band applications in a 2-μm InGaP/GaAs heterojunction bipolar transistor (HBT) process. An off-chip ...
