Abstract
The progress of the fabrication technology of the crystal resonators became to expand to VHF and UHF band beyond a traditional HF band. Along with this fact, the characteristic of the crystal resonators is demanded to be measured in these frequency bands. An international standardized measurement method, however, do not exist now. In these frequency range, all of devices and circuits work as distributed constant circuit. When we measure the characteristic of the crystal resonator, it is necessary to consider the setting portion of the crystal resonator on circuit as the distributed constant circuit. We have examined the use of the microstrip line to measure the characteristic of the crystal resonator.
