This paper introduces a recently constructed V-band and an under development W-band waveguide microcalorimeters that will serve as primary power standards in KRISS. The design scheme of the V- and W-band microcalorimeters is briefly presented, and their basic performance was checked. We propose a thermoelectric reference standard that will cover V- and W- bands. We also propose an in-house V-band...
The direct comparison technique using a transfer power standard with an adapter and its uncertainty are considered. A waveguide thermistor mount with an appropriate waveguide-to-coaxial adapter serves a new combined coaxial power standard. In order to obtain the effective efficiency of the combined standard, the phase as well as the magnitude of the adapter scattering parameters have to be known....
