Abstract :
A theoretical study of the relationship between the electrical series resistance (Rs) of an IMPATT diode and the threshold current for oscillation and the corresponding frequency has been carried out, considering the inequality of the ionization rates and drift velocities of the two types of charge carriers in silicon. The series resistance has been obtained experimentally by measuring the threshold current for oscillation and the corresponding oscillation frequency with an X-band silicon SDR device embedded in a resonant-cap cavity. The results indicate that the method is a suitable one for determining Rs, and they agree with the manufacturer´s data. The method would be suitable for determining R s for millimeter-wave diodes with appropriate values of the ionization rate ratios at maximum electric field
