In wireless applications, a low-noise amplifier (LNA) is an active network that increases the amplitude of weak RF signals to allow processing by a receiver. In a receiver chain, the first amplifier after the antenna contributes the most to the system noise figure. Although amplifiers are known to add noise and distortion to the desired signal, RF low-noise amplifiers (RF LNAs) are designed to increase the desired RF signal amplitude without adding distortion or noise.
Our broad portfolio of RF LNAs offer best-in-class signal performance including low-noise figures, high linearity, and low power. Advanced processes offer superior specifications in the smallest solution size. Our RF design expertise and robust characterization enable optimal features to significantly reduce design time.
Our wide range of GPS LNAs incorporate the lowest power in the smallest package to enable long battery life of consumer handheld devices, such as smart phones and wearables, while achieving the highest gain and lowest distortion. Our portfolio of GPS low noise amps includes Galileo, GLONASS, GPS L1, L2, and BeiDou to provide broadband navigation system coverage.
Our active antenna LNAs increase performance and reduce component count in automotive active antenna applications. Providing high performance signal amplification, active antenna low noise amps include features such as automatic gain control (AGC), power detectors, and integrated voltage regulation. The integration of these functions into a single chip facilitates the placement of a gain stage in space constricted areas at the base of an antenna.
Enables testing of RF performance with no additional circuitry. Provides 50Ω SMA connectors for inputs and outputs.
