High-breakdown AlGaAs/InGaAs/GaAs PHEMT with telluriumdoping
The authors report the fabrication and characterisation of an Al/sub 0.43/Ga/sub 0.57/As/In/sub 0.2/Ga/sub 0.8/As/GaAs pseudomorphic HEMT (PHEMT) with high channel conductivity grown by solid source MBE. The high conductivity of the channel is a direct consequence of the high sheet charge and high mobility that has recently been obtained by using ...

Precise Characterization and Multiobjective Optimization of Low Noise Amplifiers [PDF]
Although practically all function blocks of the satellite navigation receivers are realized using the CMOS digital integrated circuits, it is appropriate to create a separate low noise antenna preamplifier based on a low noise pHEMT. Such an RF front end
