Radio frequency power measurements

The need for improved accuracy in and understanding of all kinds of measurements has come with the recent rapid advances in modern technology. Radio frequency power measurement is no exception to this requirement. The basic principles of bolometric, calorimetric, and certain other types of power meters are reviewed. The methods for making accurate RF power measurements are discussed in detail. Emphasis is given to the techniques for eliminating or accounting for the errors due to mismatch, dc or LF substitution, and bolometer mount efficiency.
