7. Concluding Remarksix)
This workshop was entitled "Near Field Communications" and presented five talks. Not only application but alsocost, performance and future trend were discussed. First presentation is inter-chip communication of high-speed
digital signal which is attractive for high speed, low cast and low power consumption.
Second is Inter-chip signal transfer, which is useful for low cast assembly technique for especially millimeter wave
application. Third is Interface for near field communications by millimeter wave, which is important item frompoint of view of the users. Fourth is topics and trend of RF MEMS. Presenter is sure that RF switch will be key
technology because of low loss and high isolation. Final is body near field communication and the application.
Security system will be simple because that can be recognized through just their body without any cards. Many
attendances actively and deeply discussed their questions in order to clear those. In night session, future power
amplifier device, especially Si MOS was discussed. Also education issues for high frequency circuit werediscussed.
