The Beidou satellite navigation receiver needs to receive Beidou signals efficiently in a complex environment, and the design of receiver front-end is the key link. According to the Beidou receiver front-end system indicators, such as noise figure, gain, etc., we propose a low-noise amplifier design scheme which is based on Infineon’s broadband NPN RF bipolar transistor BFP740FED, and employ ADS to simulation and optimization tests. The results show that the low noise amplifier has a noise factor NF 35dB, gain flatness less than 0.5dB, input-output standing wave ratio less than 1.5 in the B3 band. This system has high noise performance of the amplifier, which can support the further development of Beidou navigation receiver application.
