Abstract : The patent relates to a system for deriving a constant intermediate frequency output over a band of input frequencies. The system consists of a mixer, a power splitter for splitting the output of the mixer into two segments of equal power, two band pass filters connected to the power splitter and a servo loop incorporating a variable frequency local oscillator whose output is connected to the mixer. The output of the local oscillator is controlled to maintain the output of the mixer at an essentially constant frequency.
