A synthesizer is disclosed and is digitally tuned and locked in a measured frequency. The synthesizer uses both the dual voltage control oscillator, each operating over less than an octave, in combination with the microwave doublers to produce a multi-octave RF output with low having low harmonics and free of spurious output signals thereon. The synthesizer uses a sampling downconverter that would, without the benefits of the present invention, produce an ambiguous IF output signal that is trans...
