State of the art Low Noise RF Amplifiers for a wide variety of applications are available from Castle Microwave. Our range of Low Noise Amplifiers and Ultra Low Noise Amplifiers have the following features:

• Frequencies ranging from 0.2GHz to 100GHz.

• Broadband and narrow bandwidth devices

• Single power supply

• Lightweight housing

• Appropriate coax or waveguide interfaces using a variety of technologies

Surface mount MMIC devices are also available as die or packaged parts.

A low noise amplifier is used to amplify very low-power signals without significantly degrading their signal-to-noise ratio. They increase the amplitude of weak RF signals, which assists processing as part of a receiver circuit. The primary specification parameter of an LNA is its noise figure, which is a measure of how much the LNA degrades the signal-to-noise ratio of the received signal.

Low noise amplifiers can also be used to compensate introduced loss in an RF signal path. By inserting a low noise amplifier, it will help to restore the original signal level, while ensuring the signal-to-noise ratio is retained.
