(English Abstract)
This paper introduces a 5GHz FIR filter low noise amplifier (LNA) based on a distributed amplifier and analyzes the its characteristics. The proposed FIR filter-LNA has the MA(moving average) filter characteristic which improves the frequency selectivity of the amplifier. Proto-type circuits with FR4 and ¥år=10.2 PCB have been realized and simulated using ADS (Advanced Design System). The simulation results verified that the designed LNA had a gain of about 10dB and the frequency characteristic of the MA FIR filter. It is expected that the proposed FIR filter LNA can be applicable to the various applications using an amplifier and a filter in RF systems.
