Within an RF signal chain, there is often the need to provide some signal conditioning in incoming, outgoing, or through signals. One of the most needed signal conditioning methods is amplification of signal energy, which is the key function of RF Amplifiers. Signal amplification involves increasing the amplitude of a signal, this could imply voltage, ..

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 ..

Pulsed radar are used in a variety of applications for weather sensing, marine sensing, aerospace navigation, and defense. Critical to pulsed radar performance is the behavior of the radar’s RF front-end hardware. Though pulse radars have advanced significantly in the past several years, with deep digital integration, the RF front-end hardware of these radars is ..

It may be surprising to some that low power system and device/component design share many of the same considerations as high power system design, albeit for different reasons. The goal of low noise design is to limit the amount of added noise, harmonics, spurs, and other factors that increase the noise floor of a signal ..
