Abstract :
A switchable GaAs MMIC cascode low noise amplifier for smart antenna combining at 5.2 GHz (HIPERLAN) is presented using a standard 0.6 /spl mu/m MESFET process. A gain of 12.3 dB and a noise figure of 2.4 dB are measured, drawing only 1.2 mA from a 1 V supply. A gain/P/sub dc/ figure of merit of 10 dB/mW is achieved, which to our knowledge is the highest ever reported at C-band.
