Low Noise Amplifiers

Our Low Noise Amplifiers (LNAs) are engineered to deliver exceptional signal amplification with minimal added noise, making them ideal for demanding RF and microwave systems where signal integrity and sensitivity matter most. Designed for precision performance from DC up to 50 GHz, these amplifiers provide low noise figures, high gain, and robust linearity to support critical applications in communications, defense, test equipment, and more.

Amplifiers - Low Noise Amplifiers

Our LNAs provide industry-leading noise figures (as low as 0.5 dB) across frequencies from DC to 50 GHz. Optimized for sensitivity in EW, Radar, and Satcom applications.

What Are Low Noise Amplifiers?

A Low Noise Amplifier is a specialized RF amplifier that boosts weak signals while introducing as little noise as possible. In any RF system the first stages of amplification set the overall noise performance — our LNAs are built to preserve signal quality and improve receiver sensitivity even in low-power environments.

Noise Figure (NF)

RF Components specializes in custom Low Noise Amplifier (LNA) engineering designed to meet the most demanding commercial, military, and aerospace requirements. With decades of RF and microwave experience, we deliver reliable, high-performance solutions tailored to your exact operating environment.

Extreme Temperature

We design LNAs for extreme operating conditions, including cryogenic temperatures for scientific research and high-temperature environments for aerospace and engine-mounted telemetry systems. Our solutions ensure stable gain, low noise, and long-term reliability where standard designs fail.

Form Factor

Our custom form-factor solutions include hermetically sealed packages, optimized connector placement, and high-density SMT modules. Designs are engineered to meet tight SWaP (Size, Weight, and Power) constraints without compromising electrical or mechanical performance.

Choosing the Right Low Noise Amplifier

When selecting a Low Noise Amplifier (LNA) for your system, the primary metric is the Noise Figure (NF). This determines how much noise the amplifier itself adds to the signal. For satellite receivers and sensitive radio telescopes, a noise figure below 1.0 dB is often required.

Other critical factors include:

  • Linearity (OIP3): Essential for multi-tone environments to prevent intermodulation distortion.
  • VSWR: Ensures proper impedance matching to prevent signal reflection.
  • Dynamic Range: The ability to handle both very weak and moderately strong signals without saturation.

Technical FAQ

What is the difference between Noise Figure and Noise Temperature?

Noise Figure (NF) is expressed in dB and represents the degradation of the signal-to-noise ratio. Noise Temperature (Te) is expressed in Kelvins and is often used in satellite communication systems. They are related by the formula: NF = 10 log10(1 + Te / 290).

Output Third-Order Intercept (OIP3) is a measure of linearity. A higher OIP3 allows the LNA to handle strong interfering signals without creating intermodulation products that could mask the weak signals you are trying to receive.

Yes, our Ka-Band and Q-Band LNAs are specifically optimized for 26-40 GHz ranges, featuring ultra-wideband performance and compact SMT packaging suitable for 5G phased array systems.
