Low Noise Amplifiers

MPG Solutions® designs and manufactures Low Noise Amplifiers (LNAs) for applications throughout the RF Spectrum, from HF to above 1 GHz.

Overview

MPG Solutions® Low Noise Amplifiers (LNAs) are designed to deliver exceptional performance across a wide range of RF applications, from HF to above 1 GHz. Engineered for superior signal clarity, low noise performance, and high linearity, our LNAs are integral components in Integrated Cosite Equipment (ICE) solutions and are also available as standalone units to support custom RF system architectures.

Benefits

Our SATCOM LNA and SATCOM Limiter Amplifier solutions provide high gain, low noise figures, and excellent third-order intercept points (OIP3), ensuring optimal signal reception while mitigating the impact of interfering signals. These amplifiers support mission-critical communications with industry-leading specifications and reliability.

MPG offers customizable solutions to meet specific frequency coverage, gain, and power requirements.
