Abstract
A low-noise amplifier (LNA) amplifies a very low-power signal without significantly degrading its signal-to-noise ratio. This paper provides the design of a linear low noise amplifier with the transistor BFP 640 using bilateral approach which is well-matched at the design frequency of 3.20 GHz with maximum transducer gain and low noise figure. Noise is minimized by considering trade-offs that include impedance matching and selecting low-noise biasing conditions.
