A method to improve the performance of the RF low-noise amplifier is proposed. The character of RF low-noise amplifier was analyzed,with the structure of the matching networks and the method to improve the integral performance were given.The SP model and pb model of RF amplifier were simulated based on ADS,the simulation results show that the input and the output matching networks have equivalent gain,this method can allocate parameters effectively,and can be referred to design low-noise amplifier.
