dc.description.abstract Schottky diodes are preferred and used in heterodyne receivers as a mixing element. In higher frequencies (THz band) the size of the diode especially the anode junction, becomes very small and causes reduced thermal properties compared to its lower frequency counterparts. Self-heating for these high frequency diodes becomes very significant for even a very small amount of current. In this master's thesis different methods of thermal and electrical characterization have been studied. Also different thermal characteristics like junction temperature, thermal resistance and thermal time constant have been investigated through simulations. COMSOL is the elected software for the simulations. Two commercial diodes have been analyzed and different methods of simulating the thermal properties have been discussed and presented. Also some comparisons with measurement results have been carried out. However, in all these thermal simulations the diode current is kept constant and only DC simulations have been carried out. en
