<p>PROBLEM TO BE SOLVED: To correct signal level constantly regardless of frequency switching and temperature variation in any frequency in the output frequency zone of a wireless transmitter. SOLUTION: In a memory medium 7, a plurality of data tables with linearized correction, which are corrected for linearizing input/output characteristics of a detector 4 at every frequency and every temperature, are stored. An operation part 6 selects specific linearized correction data tables based on the frequency information obtained from a frequency converter 1 and the temperature information obtained from a temperature detection element 9. From the linearized correction data tables, a level value after linearized correction corresponding to a detected output of the detector 4.</p> |
