Low-power measurement using diode type power sensors in the presence of higher harmonics

Popis výsledku v původním jazyce

At RF and microwave frequencies, power has been adopted as the primary amplitude measurement quantity for the signal. The traceability of microwave power to SI units is provided through a microcalorimeter setup typically around 0 dBm nominal power with thermistor sensors used as transfer standards. Thermistor sensors are suitable for the most accurate power measurements in metrological laboratories but they are not very suitable for most practical applications. One of the main limitations of thermistors includes their low dynamic range (max. 30 dB). For most applications, diode-type power sensors (DTPS) with significantly higher dynamic range (50 dB to 90 dB) are widely used allowing power levels in the range -70 dBm to +20 dBm to be measured. There are currently various types of DTPSs with different internal architecture which are optimized for various applications. This guide shows a method of evaluation of measurement errors caused by the presence of higher order harmonics when measured with DTPS.
