Microwave Oscillators: Multi-Band DTO: Series D60

Applications Notes for Microwave Oscillators
Simulator and Other Test Systems Applications

To obtain broadband frequency coverage, as well as to improve settling speed, two or more VCOs are combined, as shown in Fig. 1. A high-isolation RF switch is required to suppress all but the desired VCO. A switched lowpass filter is included in the output to reduce harmonic levels. The harmonic level for catalog units is specified at -20 dBc. However, -55 dBc suppression is available as an option.

Kratos General Microwave offers multi-band DTOs covering the 0.5-2, 2-6, 6-18 and 2-18 GHz frequency ranges. The units feature high speed, high accuracy and low phase noise. The specifications are summarized on page 190. The modular design of the DTOs enables the user to select narrower frequency coverage if desired. Please consult the factory for individual requirements.

For military applications, these DTOs require option G09 to comply with Military Standards. The specific environmental MIL STD requirements as well as the EMI/RFI specifications should be provided by the customer.
