Throughout the signal chain and especially at a signal input stage, RF signals for communications and sensing can be extremely weak. RF Low Noise Amplifiers (LNAs) are the most common method for increasing the signal level of these very weak signals while minimizing the introduction of signal degrading factors. Of these signal degrading factors, added ..

Low noise amplifiers (LNAs) are a critical component for telecommunication and sensing systems, as the weak receive signals often need to be at a higher signal level for optimal demodulation, digitization, driving another circuit, or for measurements to be made. LNAs are also used throughout signal chains to add gain to low power signals when ..

Though highly sensitive receivers require low noise amplifiers (LNAs) that are also sensitive to extremely weak signals, this sensitivity can also put the receiver front end LNAs at risk of desensitization, latent performance degradation, or destruction. In the presence of a signal strength at the input of an LNA that exceeds the input signal power ..
