Satellite Amplifiers Key Terms

Learn satellite amplifiers key terms to boost your signal and your knowledge
By Kristan Hart Satellite amplifiers are essential for many satellite users. Some satellites produce weak signals, and satellite amplifiers take that weak signal and give it a boost. That boost makes the signal stronger so customers and corporations receive the high-quality video and audio signal satellites are known for. Different kinds of amplifiers, various accompanying equipment and jargon are common terms you'll hear when dealing with satellite amplifiers. Satellite amplifiers key terms can help you navigate the terminology of this highly technological field.
 

Amps

Amps is an abbreviation of amplifiers. When you see "satellite amps" anywhere, it refers to "satellite amplifiers."
Try: ZD Net defines amplifiers and explains what they do. 

In-line signal amplifier, or in-line amplifier

An in-line signal amplifier, also known as an in-line amplifier, boosts signals sometimes lost by long cable runs. An in-line signal amplifier is smaller and less expensive than other types of satellite amplifiers.
Try: The product descriptions on HomeTech Solutions explain how in-line amplifiers work.

Amplifier subsystems

Amplifier subsystems help provide a power amplifier with higher gain and more output power. Amplifier subsystems are often integrated into the rack that contains other satellite equipment.
Try: OPHIR RF describes many of the technical aspects of amplifier subsystems.

Control-grid modulator

In all types of electronic communications, including satellites, the amount of power coming through the line can change instantly. A control-grid modulator helps to control the level of power to make sure there's not a power surge, which can damage electronic equipment.
Try: Integrated Publishing describes a control-grid modulator and why it's popular in portable electronic equipment.

Radio frequency (RF)

RF signals are what make satellite communications possible. RF signals are invisible electromagnetic waves that your antenna receives. RF satellite amplifiers take those signals and improve quality that may be lost because of long cable runs.
Try: Phone Scoop defines RF and explains how it helps with wireless communication.

Low power, medium power and high power

Low power, medium power and high power are terms that refer to the signal strength of the satellite. Typically, satellites that have lower power require satellite amplifiers more often than high-power satellites.
Try: You'll find definitions of low-power satellite, medium-power satellite and high-power satellite in the Glossary: Satellite and Computer Technology.
