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