Abstract :
The estimation of thermal limitations for pulse operation mode in the 8 mm-wave band of double-drift impact avalanche and transit-time (IMPATT) diodes with microwave power ≥20 W. It is shown that at pulse duration of 300 ns and amplitude of 11.3-15 A; overheating of p-n junction is 270-430°C. The boundary value of temperature of p-n junction at which IMPATT diode degradation begins is found to be 350°C.
