US Patent 7728647 Temperature compensation for RF detectors

Compensation for an RF detector includes components having different order temperature functions. The components are combined and may be adjusted by various numbers of user-accessible terminals to provide individual adjustment for factors such as operating frequency. In some embodiments, first and second-order temperature functions are generated independently and combined to provide a polynomial function of temperature with coefficients that may be adjusted. In other embodiments, the outputs of the function generators may be more complex functions of temperature with various adjustable parameters.
