  • Abstract
    In this paper we present the correlation between the impact ionization gate current with the S22 scattering parameter measured in the 50 MHz - 6 GHz frequency range in InAlAs/InGaAs/InP HEMTs. Devices with shorter gate length presenting larger I.I. gate current have shown larger inductive component in the output admittance Y22 at low frequencies.
