Development of a feasibility model for a thin-film precision power meter
Abstract
The development of a thermally coupled transducer and its evaluation circuit for a precision power meter is described. A thin film transducer made up of two temperature sensors and operating in a bridge configuration has the advantages of dc coupling for the RF circuit, very fast transient response and very good RF matching up to the GHz region.
