Summary:
This paper proposes a high selectivity low noise amplifier (LNA) for a software-defined radio (SDR) receiver. This LNA is achieved by series resonance with a high quality factor using a microstrip line and external inductor. This series resonance provides a band-pass filtering characteristic and high voltage gain.
