RF Amplifier ICs

RF amplifiers - or radio frequency amplifiers - are tuned amplifiers that increase the high-frequency signal used in radio communications. They're used in electronic circuits with other components.

Types of RF amplifiers

RF amplifiers can tune into a desired range of input frequencies. They can also provide gain, buffering and drive for fragile signals. There are several different types of RF amplifiers characterised by their frequency range, supply current, supply voltage, gain and output power.

Common types include:

  • RF amplifier power gain - if signal is too low to be useful elsewhere in the circuit, it can be increased by this amplifier. The amplifier boosts the signal level with minimum noise or distortion and can even be used with extremely low-level signals, such as those from an antenna.
  • RF power amplifier - this type of electronic amplifier converts a low-power radio-frequency signal into a higher power signal.

RF amplifiers applications

RF amplifiers have a variety of applications, including communications testing and medical diagnostics as well as voice and data communications.
