Abstract

Some aspects of measurement of I–V-curves for IMPATT diodes are considered. There were determined the main parameters of the pulsed I–V-curves for IMPATT diodes: density of critical current, voltage step in the region of negative differential resistance and avalanche breakdown region. A method for determination of p–n junction-package thermal resistance that is required for calculation of IMPATT diode operating mode is given. A possibility to use DU magnitude for prediction of early failures of IMPATT diodes was demonstrated.Рас­смот­ре­ны осо­бен­но­сти из­ме­ре­ния вольт-ам­пер­ных ха­рак­те­рис­тик им­пуль­сных ла­вин­но-про­лет­ных ди­о­дов (ЛПД).
