Abstract
High frequency power standard is quite everywhere implemented using the Microcolormeter technique. At INRiM a twin type coaxial Microcalorimeter is used to measure the effective efficiency of thermoelectric detectors from direct current up to 40 GHz. However, below 10 MHz there is a lack of sensitivity that reduces the power standard accuracy. To work around the problem, we propose to calibrate the power detectors trough RF voltage measurements in the lowest frequency band.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
