Radio frequency is measured in units calledhertz(Hz), which represent the number of cycles per second when a radio wave is transmitted. One hertz equals one cycle per second; radio waves range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz) of cycles per second. In...

This paper reviews fiber optic link techniques from the microwave and millimeter-wave transmission point of view. Several architectures of fiber optic links are reviewed. The application of MMIC technologies to the optical receivers are discussed and 26-GHz subcarrier transmission experimental works are...
PURPOSE: To increase a leakage preventive effect by regulating a microwave transmitted in multi-directions by furnishing excellent leakage and discharge preventive shielding structure by a quadruple shielding effect. CONSTITUTION: Leakage of high frequency is primarily reduced and eliminated by constitution ...
