Abstract :
A dual-band low noise amplifier (LNA) which can operate at both 2.4GHz and 5.2GHz frequency band is proposed. Input matching, noise matching and narrow gain are achieved at 2.4GHz and 5.2GHz frequency band by switching the equivalent inductance and resistance of input and output circuits. The proposed LNA is designed in a TSMC 0.18um CMOS technology with a supply voltage of 1.5V. The LNA has gain of 11.8 dB and 16 dB, noise figure of 3.6 dB and 2.5 dB at 2.4GHz and 5.2GHz frequency band respectively while dissipating power of 4.5 mW at both frequency bands.
