ABSTRACT:
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.
