AbstractThis paper presents the design of low noise amplifier for WLAN front-end applications using enhancement mode technology. Typical single frequency LNA is required to operate with low noise, high gain and good linearity at 2.4GHz. The design adopts feedback, and balancedtopology to counter the problem of conventional LNA design which has difficulty in meeting the design specification.The measured result show the proposed LNA has noise figure (NF)< 2dB, gain>10dB and with S1 1 and S22 <-10dB at 2.4GHz
