Abstract
A wide band feedforward lineariser amplifier we have developed is described. In particular, we report the IM3 improvement obtained without automatic adaptive control circuits, indicating the possibility of realizing small, low-cost products. We designed a lineariser amplifier for 2.5 GHz band to demonstrate the effectiveness of our approach and measurement revealed the wide band linearising capability of over 100 MHz.
