Abstract

A 1.5 V operating GaAs 2/spl sim/9 GHz ultrawide-band MMIC amplifier for portable wireless LAN, microwave link and satellite communication applications has been developed. This amplifier has 16/spl plusmn/1 dB gain and more than 10 dB input and output return loss in the 2/spl sim/9 GHz frequency range with 118 mA operating current. Measured 1-dB compression power is 13 dBm at 0 dBm input power and minimum noise figure is 4.8 dB. When operated at 3 V and 128 mA, this amplifier has up to 18/spl plusmn/1 dB gain, 18 dBm 1-dB compression power, more than 10 dB return loss and 4.9 dB minimum noise figure.
