An automatic power control system compensates for temperature variable components in a broadband signal generator by providing a reference signal generating circuit that is temperature matched with an automatic level control feedback circuit. The temperature matched components are either monolithic or placed in substantial thermal contact with one another. The signals from the matched signal paths are input to a summing circuit such that the effect of any temperature variation in one path is exactly offset by the corresponding temperature variation in the other path.
