The amplitude of the tuning rises with growth of the impedance step between microstrip lines forming the resonator. Maximum of tuning takes place when the ratio of low-impedance part length to high-impedance part length reaches 1/2. Ability is demonstrated to design a filter with a constant absolute bandwidth on filter tuning.","PeriodicalId":226991,"journal":{"name":"2004 14th International Crimean Conference \"Microwave and Telecommunication Technology\" (IEEE Cat.

The device is intended for use in medical applications and has to provide a higher operating frequency range, and deliver coherent emission. One way to tackle these problems is to multiply the frequency of the original highly-coherent Gunn-diode signal by a multiplier component built around a Schottky diode. The work presents the technique for designing a highly-coherent 75-160 GHz EHF EMR source on the basis of commercially available 37-40 GHz Gunn diodes and multiplier Schottky diodes manufactured under a planar technology. The suggested concept offers a cost-effective upgrade for commercially produced EHF-therapy equipment.","PeriodicalId":226991,"journal":{"name":"2004 14th International Crimean Conference \"Microwave and Telecommunication Technology\" (IEEE Cat.
