PMI Model No. DTO-218-CD-1 is a digitally controlled oscillator (DTO's) covering the frequency range of 2.0GHz to 18.0GHz. This model is designed to withstand stringent military ground or airborne environments. Incorporated in the design is the latest internal digital calibration techniques such that frequency drift over the operating temperature range is minimal. This unit offers fast switching speeds and a stable frequency output with low phase noise.
