A broadband amplifier chip based on AlGaAs/GaAs/AlGaAs quantum well FETs with 0.3 micrometer gate length has been designed and fabricated. The amplifier can be operated with single-ended or differential inputs with an input resistance of 50 Ohm. The output signals are differential with both internal load resistance at 100 Ohm, the chip area is 1x1 mm2, and the power consumption is about 375 mW.
