Average power-handling capability of microstrip lines
Abstract
An expression for the average power-handling capability (APHC) of microstrip lines is derived by considering the heat generated in the strip conductor and the dielectric substrate. The analogy between electrostatic fields and heat-flow fields is used for calculation of the rise in temperature of the strip conductor. The computed value of APHC for a 50-ohm line on alumina substrate (0.06-cm thick) is 5.26 kW at 10 GHz whereas the corresponding figure for polystyrene substrate is 126 W.
