In this paper, an 8 – 18 GHz wideband low noise amplifier (LNA) with an active balun fabricated in a 0.13-μm SiGe BiCMOS technology was presented. The LNA achieves 16dB of gain with 1.5 dB variation over the 8GHz to 18 GHz frequency band and a matched input with less than -9 dB of reflection. The minimum noise figure (NF) is 5 dB at 8GHz and increases to 6 dB at 18GHz. The measured IIP3 is -15-...

What is a Low-Noise Amplifier? Digital signal processing (DSP) systems require interfaces to the analog world. The first amplification stage in a radio receiver is typically the tuned low-noise amplifier (LNA), which provides enough amplification to the input signal to make further signal processing insensitive to noise. Although the primary goal in LNA design is to minimize the system noise fi...
