High-resistivity GaAs grown at low temperatures by molecular beam epitaxy was used as the surface passivation layer of MESFETs. When these MESFETs are biased in the saturation region, the frequency dispersions of the transconductance and output resistance are reduced compared to those of a MESFET without a passivation layer.
