X- and Ku-band YIG-film tuned low noise oscillators

X and Ku-band YIG (yttrium iron garnet)-film tuned oscillators (YTOs) with phase noise below -95 dBc/Hz 10 kHz from the carrier and a high output power of more than +10 dBm without the use of buffer amplifiers have been developed. The authors describe the design criteria used to realize these high-performance YTOs. The YTOs are characterized by excellent linear tuning, low-phase noise over a relatively wide band, and small frequency drift with temperature. These oscillators are ideal for data and video transmission systems utilizing surface microwave links as well as satellites.<
