Designing A 10 GHz Low-Noise Amplifier

The critical role of a low-noise amplifier (LNA) for a radio receiver front end involves amplifying very low-power signals received by the antenna that are often just above the noise floor without significantly lowering the signal-to-noise ratio. LNA designers must find ways to minimize noise for this process by considering trading off factors such as impedance matching, choosing the appropriate amplifier technology, and selecting low-noise biasing conditions.
