Abstract:

Matched microwave resistors with the different substrate materials have been investigated. Theoretical analysis of the resistor’s thermal properties is performed using a multyphysical model of thermal and electronic transport. Electromagnetic and heat transfer equations were solved simultaneously using finite element method. Distributions of the temperature and electromagnetic field in the volume of substrate within a frequency range 0…50 GHz have been presented. Thermal parameters of the microwave resistors with three different substrate materials have been analyzed theoretically using numerical computation results.
