Precise characterisation of liquid materials in 1 ÷ 50 GHz range
QWED offers TE01δ mode dielectric and cavity resonators and Fabry-Perot Open Resonator (FPOR) for precise characterisation of liquid materials. Wide application spectrum covers e.g.
- PCBs Immersion Cooling - for characterisation of electronic coolants
- Food Industry - for characterisation of liquid materials e.g. oils

TE01δ mode dielectric and cavity resonators are single-frequency solutions and are offered in the range from 1 to 25 GHz whereas FPOR is a wideband device covering a spectrum of 15 ÷ 50 GHz. Moreover, the fixtures used <25 GHz are adapted to enable measurements of dielectric properties at elevated temperatures up to 100 oC.
