Abstract：

This　paper　presents　design　and　implementation　of　a　dual-band　LNA　using　a　0.35　μm　SiGe　HBT　process　for　0.9　GHz　GSM　and　2.4　GHz　WLAN　applications.　PCB　layout　parasitic　effects　have　a　vital　effect　on　circuit　performance　and　are　accounted　for　using　electro-magnetic　(EM)　simulation.　Design　considerations　of　noise　decoupling,　input/output　impedance　matching,　and　current　reuse　are　described　in　detail.　At　0.9/2.4　GHz,　gain　and　noise　figure　are　13/16　dB　and　4.2/3.9　dB,　respectively.　Both　S11　and　S22　are　below　-10　dB.　Power　dissipation　is　40　mW　at　3.5　V　supply.　©　2013　Chinese　Institute　of　Electronics.
