The improvement of Low Noise Amplifier (LNA) of radar systems was a necessity especially for military processes. LNA is the first step of any RF Receiver construction in wireless system. The LNA has more affected on any RF receiver performing. The purpose of this paper is to design a broadband LNA based on compensated matching network technique in order to get high stable gain, low noise figure (NF) for radar systems applications at centre frequency 1.8 GHz with band width 800 MHZ. By the benefit of using the Advance Design System (ADS) the design and simulation can be performed. The design has been executed using Low noise transistor BFU 730F With the usage of NF of 0.74-0.84 dB with class A bias circuit, Collector current is calculated to be 10.1mA, base current is 35.2µA with supply voltage of 2.25V. The new design is used to achieve high stable amplifier gain 20.4 dB. To enhance the LNA’s stability, we used micro strip lines and compensated matching network technique to achieve good results
