The S band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a part of the microwave band of the electromagnetic spectrum covering frequencies from 2 to 4 gigahertz (GHz).

S波段（英語： S band ）是指频率在2-4 GHz的无线电波波段。NASA和欧洲空间局的深空站通用的S波段通信频率范围为上行2025-2120 MHz，下行2200-2300 MHz。 [1] [2]

2020年12月13日 · S-band (2–4 GHz) Weather radar, surface ship radar, and some communications satellites, especially those of NASA for communication with ISS and Space Shuttle. In May 2009, Inmarsat and Solaris mobile (a joint venture between Eutelsat and Astra) was awarded each a 2×15 MHz portion of the S-band by the European Commission.

2019年8月11日 · The S-band as defined by IEEE is a frequency range from 2 to 4 GHz. IEEE uses letters to signify a range of frequencies from 1 to 170 GHz. This band is mostly used for mobile communications, including IMT-2000/UMTS, mobile satellite communications and weather/ship radar systems.

S band systems are known for their reliability and resistance to signal interference which makes them suitable for critical applications in aviation and maritime industries. S band radar provides more accurate data due to their relatively smaller wavelengths which is used for weather forecasting and air traffic control (ATC).

In the S-band, a CR GSO satellite uplink/downlink (1980-2010 and 2170-2200 MHz) (scenario F) is considered. Here, hybrid satellite-terrestrial networks with mobile user terminals are deployed utilizing potentially different broadcast and interactive technologies in the …

2023年5月17日 · S-band. The S-band, ranging from 2 to 4 GHz, is commonly used for weather radar, surface ship radar, and some communications satellites, especially those used by NASA to communicate with the International Space Station.

The S-band falls within the microwave frequency range, typically ranging from 2 to 4 gigahertz (GHz). It is widely used in various satellite applications, including telecommunications, remote sensing, weather monitoring, and scientific research. The S-band offers several advantages for satellite communication.

MACOM’s GaN-on-SiC products are well suited for pulsed and CW S-band applications. With a variety of power levels, high gain/stage and high power-added efficiency, MACOM’s products support continuous improvements in SWAP-C benchmarks, thereby supporting the next generation of radar systems in areas such as air traffic control, weather radar ...
