Accurate measurement of microwave power in the IEC: R-70 (WR-138) waveguide transmission line

We compare the accuracy of different techniques to measure guided RF power at 6.83 GHz. The transmission line is a standard rectangular metallic waveguide IEC: R-70 (WR-138). We used three calculable standards including a waveguide calorimeter, a coaxial calorimeter, and an atomic (quantum based) po...

Summary:We compare the accuracy of different techniques to measure guided RF power at 6.83 GHz. The transmission line is a standard rectangular metallic waveguide IEC: R-70 (WR-138). We used three calculable standards including a waveguide calorimeter, a coaxial calorimeter, and an atomic (quantum based) power meter based on laser cooled rubidium atoms.
