摘要

研制了一种适用于便携式无线局域网、微波链路和卫星通信的1.5 V工作GaAs 2/spl sim/9 GHz超宽带MMIC放大器。该放大器在2/spl sim/9 GHz频率范围内具有16/spl plusmn/1 dB增益和超过10 dB的输入和输出回波损耗，工作电流为118 mA。在0 dBm输入功率下，实测1 dB压缩功率为13 dBm，最小噪声系数为4.8 dB。当工作电压为3v和128ma时，该放大器具有高达18/spl plusmn/ 1db增益，18dbm 1db压缩功率，10db以上回波损耗和4.9 dB最小噪声系数。

1.5 V ultrawide-band GaAs monolithic amplifier for portable wireless LAN and satellite communication applications

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.
