The purpose of activity - research of temperature effect and high of a potential hill on a cathode contact GaAs of the diode on an overall perfomance of generators of the second and third harmonics both range of electronic and mechanical modification in the temperature range 300... 500 K. Method of testing - mathematical simulation of physical processes in GaAs Gunn diodes both generators of the second and third harmonics on their basis. Is pointed, that with temperature rise of an active area of a Gunn diode with metallic m-n by a cathode contact and length of an active area of the diode 2,5m up to 500K, by activity on frequency of a second harmonic the maximum efficiency of generation decreases up to 3% ( at T=300 K efficiency = 5%). In Gunn diodes with 1m the efficiency at generatio n on a second harmonic has decreased up to 1% at 500 K (at T=300 K efficiency =1,8%). By activity on frequency of a triple-frequency harmonic the efficiency of such diode descreases from 0,6% (at T=300K) up to 0,3% (at T= 500 K).
