The Advantages of GaAs
Updated : 2022-01-24

GaAs has some better electronics than Si, allowing GaAs to be used at speeds greater than 250 GHz. If the equivalent GaAs and Si components operatesimultaneously at high frequencies, the GaAs produces less noise. Also because GaAs has a high breakdown pressure, GaAs is better suited to operate
