Abstract: | The new method of the CW intensive noise signals excitation in millimeter wave band has been studied. With this aim in mind the O-type Backward Wave Oscillators, operating in chaotic oscillation regime, are proposed to use. The noise sources, based onBWO, have a high efficiency, universal power spectrums and feasibility of electronic tuning of the noise signal frequency in the relative range of 4–10%. Low voltage noise sources, operating in the bands needed over the range from 30to 60GHz, make possible output power of 8 – 25W and 4W respectively and 3 –dB power spectrum width more than 300M H z. Application of the suitableBWO offers to excite the noise signals in decimeter and centimeter ranges too. |
