A Si BJT RF dual band receiver IC for DAB

Concurrent multiband low-noise amplifiers-theory, design, and applications

“…5 While the NF is a useful parameter in practice, it is an incomplete measure of an LNA's performance, as it is desirable to have a low NF while maintaining a high gain. For example, feedback can be used to reduce F as close to unity as possible, at the price of lowering the gain in the process [28], [47].…”
