Digitally Tuned Oscillators: Series D60 - Single-band DTO

 
 
 
Application Notes for Microwave Oscillators

Single Band Digitally Tuned Oscillators Series D60


Digitally Tuned Oscillators

The Series D60 single-band DTO covers the frequency range of 0.5 to 18 GHz in 6 DTOs. Fig. 2 is the basic block diagram of the single band DTO.

When constant deviation bandwidth is required across the entire frequency band of the DTO, Option 2 should be used.

For military applications, these DTOs requires 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.
