Two-Stage Low-Noise Amplifier; Simulation and Comparison Based BJT at 900-1000MHz

The paper presents a simulation study on the design of a two-stage low-noise amplifier (LNA) using a (BJT). The simulation results were compared to key performance metrics at frequencies of 900 MHz and 1000 MHz. At 900 MHz, the amplifier achieves a gain of 25.7 dB, a noise figure of 4.6 dB, and stability of 7.6 dB. At 1000 MHz, the gain decreases to 17.6 dB, the noise figure improves to 1.8 dB, and stability increases to 9.4 dB.
