Millimeter wave power measurement above 110 GHz

Abstract

With the power measurement standards above 110 GHz undefined, it is left to individuals to devise the methodology of determining the RF power above 110 GHz. This paper details a simple and repeatable method in measuring RF power up to 1 THz using a calorimeter. Calorimeter power measurement is based on the black body absorption principle - a change in temperature between a known power absorbed to an unknown power absorbed. Performance of various millimeter wave bands RF power data are presented and compared.
