Establishment of RF attenuation standard in the frequency range of 30 GHz to 50 GHz conducted in NMIJ is described. Measurement system is constructed by adopting the simple and high stable IF receiver technique using a resistive step-attenuators, as an IF attenuation reference standard operated at 30 MHz and a general-purpose receiver, as a level detector. Traceability of the system is ensured by...
An automated 1-kHz null-balance receiver for the RF attenuation measurement system based on the dual-channel intermediate frequency substitution method was constructed and examined. A commercial programmable inductive voltage divider (IVD) was applied as its attenuation reference; however, highly accurate voltage ratios were ensured by the developed voltage ratio standard system. It is shown that...
