Abstract :
A designed LNA can support the dualband; 2.3~2.5 GHz and 5.1~5.9 GHz. Switched inductor and switched capacitor is adopted for frequency selection. In switched inductor and capacitor matching network, the optimizing techniques to minimize the insertion loss are explained and self-matched capacitor is proposed for easy flexible impedance and noise matching in the various frequency bands. As using switched inductor and capacitor matching network, a designed LNA can support IEEE 802.11a/b/g in 2.4 GHz and 5.2 GHz. The performances of LNA are comparable with those of LNA for single standard due to self-matched capacitor and optimized switched inductor matching network. The dualband LNA is designed with small size (0.5 mm2) by reducing the number of inductors.
