| Abstract: | The modern radar system requires higher performance of receiver.The Low Noise Amplifier can reduce the noise of the system and improve the sensitivity of the receiver,which is the important part for receiving system.The LNA is designed for the front of radar receiver.This paper uses the integrated chips ATF36163 to complete the circuit design and conduct the sensitivity analysis of the parameters through RF circuit parameter illustration.The results show that the LNA after the sensitivity analysis not only conforms to the specifications of the receiver,but also makes the performance more stable. |
