Hall transducer as an UHF power indicator
High and Ultrahigh Frequency Measurements
Hall transducers made of n-type germanium can be used as sufficiently efficient power indicators in the long-wave portion of the UHF range for medium power. A wattmeter of that type using a Hall transducer described above in conjunction with high quality resonators has a linear scale and a sensitivity of 1 μ V per 4 m W. The error in measuring power evaluated by deviations from the mean does not exceed ±5%.
