Spectrum Microwave offers a complete line of Digitally Tuned Oscillators (DTO). These custom designed assemblies consist of a select number of sub-band VCOs covering customer specific frequency ranges between 2GHz and 18GHz. The sub-band RF outputs are selectively switched to a common RF output port. Sufficient sub-band overlap insures full band coverage. Digital tuning is via a 16 bit, parallel input word. Several bits are used for selecting the desired sub-band and 12 to 14 bits are used for frequency tuning.
Silicon semiconductors are used to provide the best possible phase noise and post tuning drift performance. Hybrid MIC technology reduces overall package size and helps ensure overall system reliability. Fast settling time and excellent spectral purity make Spectrum DTOs ideal for simulators and other EW applications.
