  • A Low-Noise Amplifier (LNA) is a critical component in RF front-end design, as it amplifies weak signals with minimal noise, preserving the signal-to-noise ratio (SNR). It is typically the first stage in a receiver system, where the overall noise figure (NF) is primarily determined by this block, making low-NF design essential.

    In Satellite Communication (SatCom) applications, where received power levels can be as low as -100 dBm, even a 0.1 dB reduction in Noise Figure (NF) can improve receiver sensitivity and enhance system performance. Thus, optimizing LNA performance is crucial for ensuring high receiver sensitivity and reliable communication.

    In this thesis, methods for noise reduction in LNA design will be investigated and implemented using SiGe HBT technology.
