A concurrent dual-band low noise amplifier with gain enhancement topology for 2.4/5.2 GHz applications
: This paper presents a dual-band low-noise amplifier (LNA)operating at 2.4/5.2 GHz for wireless local area network (WLAN) applications. The LC parallel resonance and LC series network are adopted to achieve input impedance matching and noise matching simultaneously at dual-band. Besides, a small-size capacitor with a coupled inductor is added for gain-enhancement. The simulation results show that the LNA has gains(S21) of 17.1 dB and 8.5 dB with a noise figure of 3.6 dB and 3.3 dB at 2.4 GHz and 5.2 GHz, and input return loss(S11) of -15.6 dB and -13.8 dB while output return loss(S22) of -11.7 dB and -20.7 dB at two operating frequencies, respectively. Therefore, the proposed LNA structure is an attractive alternative to WLAN applications.
