This paper presents the design and implementation of a C-band 6-8 GHz wideband low noise amplifier (LNA). The design is based on balanced structure. The compensated matching networks are designed to obtain gain flatness, two Wilkinson couplers are used to obtain good input and output VSWR, a section of microstrip line is introduced between the source and ground to improve the stability. The measured gain is 12±0.5 dB and noise figure is less than 1.5 dB, the input and output VSWR are better than 1.7. The LNA with broad bandwidth, flat gain, low noise figure and high stability can be used in wideband RF receivers.
