How to Choose a Low Noise Amplifier

Frequency Range and Bandwidth

Start by identifying the operating frequency range of your system and whether you need narrow-band or wide-band performance. Narda-MITEQ offers low noise amplifiers across an exceptionally broad frequency range, making it easier to match the amplifier to your exact RF, microwave, or millimeter wave application.

Noise Figure and Noise Temperature

For weak-signal receive paths, noise figure and noise temperature are often critical selection criteria. Use the search tools below to narrow products by maximum noise figure or maximum noise temperature to better align the amplifier with your receiver sensitivity goals.

Gain, Output Power, and System Requirements

Required gain and available output power affect the way the amplifier fits into the larger signal chain. Search by gain and 1 dB compression output power to identify models that provide the needed signal boost without compromising your system design targets.

Package Type, Environment, and Application Fit

Mechanical integration, environmental conditions, and application type also matter. Narda-MITEQ offers a variety of package options and specialized low noise amplifier families to support space, SATCOM, cryogenic, waveguide, wideband, and other demanding use cases.
