Low DC power monolithic low noise amplifier for wireless applications at 5 GHz

A two stage monolithic integrated low noise amplifier for applications in the wireless data frequency range of 5 to 6 GHz has been designed. A noise figure of 3.5 dB with a gain of 15 dB has been achieved using enhancement MESFETs only. The LNA draws 3 mA from a 3.3 V supply, achieving a gain/P/sub Dc/ figure of merit of 1.5 dB/mW.
