Design of low noise amplifier using feedback and balanced technique for WLAN application
Procedia Engineering, 2013•Elsevier
This 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 2.4 GHz. 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 2.4 GHz.
