Abstract

The dc electrical characteristics of NPN RF power transistors were studied systematically before and after 175 MeV Ni¹³⁺ ion and Co-60 gamma irradiation in the dose range from 100 krad to 100 Mrad. The transistor parameters such as excess base current (ΔI_B= I_Bpost-I_Bpre), dc current gain (h_FE), and collector-saturation current (I_CSat) were studied. The base current (_IB) was found to increase significantly after irradiation and this in turn decreases the h_FE of the transistors. Further, the output characteristics of the irradiated devices exhibit the decrease in the collector current at the saturation region (I_CSat) with increase of radiation dose.
