Low Noise Amplifier LNA ICs
Boost the data-rate and reception quality of your wireless application with Infineon’s low noise amplifiers
Low Noise Amplifier LNA ICs subcategories
A low noise amplifier (LNA) amplifies a very low-power signal without significantly degrading its signal-to-noise ratio. When regular amplifiers amplify signals, additional noise is often introduced to the system. However, by using an electronic LNA, this noise can be significantly reduced.
Infineon’s range of low noise amplifier ICs improve receiver sensitivity and thereby achieve the ultimate user experience. Our portfolio of MMIC RF LNAs is continuously updated to satisfy the ever-changing market requirements with custom made products for each application. Highly integrated in the smallest package, our LNA MMICs come with ESD protection and low power consumption, ideal for battery-operated mobile devices. What's more, our innovative SiGe technology delivers lower noise than silicon alternatives and performance comparable to more expensive GaAs counterparts.
Profiting with all the aforementioned advantages of our LNA MMICs, you will increase the system sensitivity tremendously, and the users of your 4G/5G, GPS, Mobile TV, Wi-Fi, and FM portable devices will enjoy features such as high data-rate reception, fast and precise navigation, and smooth high-quality streaming even in the worst reception conditions e.g. dense cities, underground, indoors, etc.

Infineon’s extensive portfolio of LNA MMICs offer high gain and an ultra-low noise figure. This allows frontend losses to be significantly improved and increases data rate. Infineon has developed a comprehensive product range low noise amplifier ICs, that include gain step LNAs and multi-state LNAs to improve 4G/5G system sensitivity.
Improve receiver sensitivity
To develop this technology, our R&D experts set themselves the target of reducing the gap between Gamma Opt point (location of optimum source impedance for minimum noise figure) at 5-6GHz and 50Ω to boost RF receiver sensitivity. This allows customers to quickly design systems supporting input matching without requiring any external matching components.
Benefits include a low noise figure (less than 1dB at 5-6GHz at application level and 0.75dB NFmin at transistor level), best power gain (around 15dB) at application level, and 22dB maximum power gain at application level, reduced BOM, smaller PCB footprint, and best linearity at lower supply voltages. Robustness against ESD and high input power thanks to integrated ESD protection at the input and output.
