Abstract :
This paper describes a 10-kilomegacycle power meter using a bead thermistor for a power detector and having full scale sensitivities from +6 decibels referred to 1 milliwatt (dbm) (4,000 microwatts) to ¿14 dbm (40 microwatts) selected in 2-decibel (db) steps. Absolute calibration from built-in d-c standards is provided.
