What are RF amplifiers used for?
RF amplifiers stand for radio frequency amplifiers, which usually are used to amplify a low-power RF signal into a higher power signal from a few MHz to the multi-GHz range. RF power amplifiers generate a completely new output signal based on the input. Typically, RF amplifiers are applied to the antenna of a transmitter.
The main characteristics of an RF amplifier are its gain, noise, bandwidth, efficiency, linearity, and other performance parameters. Considering these characteristics as the main classification criteria, we can distinguish between various types of amplifiers designed to offer performance optimized for specific application scenarios. KeyLink’s RF power amplifiers are categorized according to their usage. Below are several categories of RF amplifiers. Click on the category titles for the complete product listings.
RF Power Amplifiers – RF power amplifier used for high-power amplification at low microwave frequencies.
Broadband Amplifiers – RF amplifiers with a flat response over a wide range of frequencies.
Narrowband Amplifiers – Amplifiers designed for optimum operation over a narrow band of frequencies.
Pulse Amplifiers – Amplifiers designed to amplify RF pulses generated by an electrical device without altering its waveform.
Low Noise Amplifiers – RF amplifiers primarily used in communication systems to amplify weak power signals captured by an antenna.
Limiting Amplifiers – Delivering stable compressed output power across a wide input range.
