The paper focuses on a comparative study of transistors of different dimensions from nine prominent low noise HEMT processes around the world. The transistors include a combination of pHEMTs and mHEMTs based on GaAs and InP substrates with gate lengths ranging from 150nm to 70nm. The Square Kilometre Array telescope will require more than 30 million low noise amplifiers (LNA). Importance of power consumption and variation of ambient temperature of the amplifiers over time and also location are… CONTINUE READING
