Abstract

A highly linear Low Noise Amplifier (LNA) using a flexible feedforward linearisation scheme is described. The wideband LNA is designed for use in the frequency spectrum between 1 and 2GHz. It has a tuneable linearity profile which allows it to be adjusted for wideband moderate linearity or narrowband high linearity. The linearity can be tuned so a wideband Third Order Intercept Point (IP3) improvement of 4dB can be achieved from 1.3 to 1.7GHz or a narrowband (1MHz) 13dB improvement can be realised anywhere between 1.1 and 1.7GHz
