“…That is, the RF-DC difference δ N of a reference standard at its type-N connector can be transferred to the middle of the tee using (15). The evaluated δ T can be used in (2) as δ Std to determine the RF-DC transfer difference δ DUT of the TVC under test, the NRC CTVC in this paper.…”

“…5 to the results evaluated by NMC, A*STAR for traveling standards in the key comparison CCEM.RF-K4.CL [10], it is found that the working frequency range of the CTVC designed by NRC could be extended up to 1 GHz. Furthermore, if reversely using (15) and (11), the RF-DC difference δ at the middle of the tee of a CTVC could be transferred to the calibration factor K of a power sensor. The CTVC designed by NRC with a calculable frequency characteristic, therefore, becomes a good candidate as a reference standard for calibrating a power sensor in terms of its RF-DC difference δ.…”

“…During the calibrations, the RF-DC transfer difference δ N of the reference standard NRV-Z51 at its type-N input connector is determined in terms of its calibration factor and the voltage reflection coefficients using (11). δ N is then transferred to the middle of the built-in internal tee using (15), and later works as δ Std in (2).…”

“…For this reason, besides using the well-established calibration method based on a thermistor mount [13]- [15], we decided to characterize the CTVC RF-DC difference in terms of the voltage reflection coefficient (a parameter which can indicate the degree of impedance mismatch) at the input of a thermistor mount. In the following, the proposed method is described in detail.…”

“…In the frequency band 100 MHz to 1 GHz, the characterizations of the TVC RF-DC transfer difference are carried out either in terms of the power and impedance using thermistor mounts [13], [14], or in terms of the effective efficiency of a thermistor mount and the RF and DC conductances at its input connector [15].…”

In this paper, we present a performance evaluation of the RF-DC transfer difference for a calorimetric thermal voltage converter (CTVC) designed by the National Research Council of Canada (NRC) at frequencies up to 1 GHz. In the first part of this paper, we describe a bilateral comparison of the RF-DC difference standards between the NRC and the National Metrology Centre of the Agency for Science, Technology and Research of Singapore, in the frequency band from 1 kHz to 100 MHz. A good agreement is observed between the two laboratories using the CTVC as a traveling standard. In the second part of this paper, we evaluate the performance of the CTVC at higher frequencies up to 1 GHz. In this part, RF-DC difference of the CTVC is mathematically modeled and experimentally evaluated in terms of the calibration factor of a thermistor mount and the reflection coefficients at its type-N input connector.Index Terms-AC-DC difference, calorimetric thermal voltage converter (CTVC), mathematical modeling, RF-DC difference.
