A dual-band GaAs FET low noise amplifier (LNA) with an input LC-tank circuit is designed using inductance source feedback for wireless LAN, and output matching is realized with low-pass Cheyshev filter impedance transforming circuit. Some design techniques for dual band LNA have been developed including input and output design equations. The measured results shows close agreement with the predicted performance.
