A 4.4 to 5 GHz SiGe low noise amplifier

This paper describes a low noise amplifier (LNA), designed for a 0.25 mmSiGe process, operating in the 4.4–5 GHz band with a noise figure of 2.2 dB. A power gain of 12.8 dB at 5 GHz has been achieved with a power consumption of 23.77 mWusing a 2 V power supply. The input power at 1 dB output power compression is 6:2 dBm. # 2003 Elsevier B.V.
