Like with other key RF/microwave component and device parameters, accounting for power extremes in RF design and system integration requires a nontrivial amount of additional considerations. If the RF signal is optimized for other performance factors, such as noise, linearity, phase noise, or other signal quality factors and the signal power is well within the ..

A ground station, earth station, or earth terminal is the terrestrial radio system used in extraplanetary telecommunications with spacecraft and satellites. Ground stations are used to communicate, bidirectionally, with satellites and spacecraft, or receive electromagnetic energy in the radio frequency spectrum from astronomical sources. Given the nature of extraplanetary communications, ground stations and satellites/spacecraft typically ..

Ultra-sensitive systems depend on receiver components with as low an added noise figure as possible. Any added noise figure in the receiver chain reduces the signal-to-noise (SNR) of the receiver, and is cumulative. Hence, for each component in the receiver chain contributing noise, the noise floor of the receiver raises. A common method to reduce ..

Synthetic aperture radar (SAR) and inverse SAR (ISAR) are methods of using radar to map a stationary object, more usually terrain. SAR/ISAR systems are deployed on aircraft or satellites that move at high velocities in respect to the surface of the earth or potentially any stationary object or terrain. SAR/ISAR benefits from the phenomenon that ..
