Various Uses of Amplifiers

Amplifiers are developed to amplify weak signals. They are available in various types to fulfil different requirements of users. Let’s discuss the types and their uses –

Low Noise Amplifier (LNA)

It performs the same function of amplifying the signals from very low power and without significantly degrading its signal-to-noise ratio. It is named LNA after this specialty. A conventional amplifier increases both the signal and noise received in the input. It is majorly used in medical instruments, radio communications systems, and electronic equipment, etc.

Amplifiers RF

These devices amplify the varying input signals and produce the output with larger amplitude with varying signals in the same way as in input. They are available in different types such as Low noise, Pulse, Bi-directional, Multi-carrier, and Buffer. Its applications include defence components, electromagnetic compatibility (EMC) testing, medical diagnostics, and communications testing.

Microwave Amplifiers

Microwave amplifiers or Traveling wave tube amplifiers (TWTAs) are designed for high power amplification at low microwave frequencies. They are used to amplify across a broad spectrum of frequencies. However, usually. Its applications are Passive Intermodulation Testing (PIM), Intermodulation Testing (IM), and Adjacent Channel Power Testing. It is also used for Multi-tone testing, Power handling, EM Immunity Testing, and High Signal Level Testing, etc.

Solid State Power Amplifier (SSPA)

SSPA is the alternative to applications using Traveling Wave Tube (TWT) Amplifiers currently. It is preferred because of its high performance and reliability, and most importantly it is cost effective. It is used in Airborne, Missile, Radars, and Communications.

You can buy any of them based on your requirements. All the types in various variants are available online at the Raditek’s website
