A Switchable Single/Double-band Low Noise Amplifier

摘要：

This paper presents a switchable single/doubleband, low noise amplifier (LNA) for WLAIS and WiMax systems. The LNA uses wideband bandpass filters and a capacitor of reduced high frequency signals at input matching networks. At the inter stage, using a series resonator increases gain at high frequency. To obtain a small chip size, this study used two center tapped inductors and a switch. This study simulated design using a TSMC 0.18um RF CMOS 1P6M process. The power gain of the LNA was 19.35 dB at 2.4 GHz, 19.83 dB at 3.S GHz, and 17.3 dB at 5.2 GHz. Noise figures were 2.9 dB at 2.4 GHz, 2.37 dB at 3.5 GHz, and 2.35 dB at 5.2 GHz. The S,, and S22 were lower than -10 dB for all desired frequency bands. The power consumption was 6.97 mVV. The total chip area was 0.82*0.87 mm*mm.
