The static and high frequency properties of GaAs and InP impatts have been investigated for lower microwave and higher millimetre-wave frequencies using the computer simulation programmes developed by the authors. The profiles of negative resistance and reactance in the depletion layer of SDR and DDR devices based on GaAs and InP and their admittance properties have been investigated. The results indicate that InP impatts of the SDR and DDR varieties have higher drift zone voltage, higher negative resistance and higher negative conductance as compared to their GaAs counterparts, both in the microwave frequency and in the millimetre-wave frequency ranges. It is thus observed that higher radio-frequency power can be obtained from InP devices than from GaAs devices.
