111ITU Model for Indoor Attenuation — The ITU Indoor Propagation Model, also known as ITU Model for Indoor Attenuation , is a radio propagation model that estimates the path loss inside a room or a closed area inside a building delimited by walls of any form. Suitable for appliances… …
112RF MEMS — The MEMS acronym stands for Micro Electromechanical System and is used to refer to components of which sub millimeter sized parts need to move for the components to have electronic functionality. RF MEMS passives, such as capacitors, inductors,… …
113Weber Research Institute — The Weber Research Institute (known prior to 1985 as the Microwave Research Institute) is a research group at the Polytechnic Institute of New York University. The institute s research focuses on electromagnetics, including electromagnetic,… …
114Distributed amplifier — Distributed amplifiers are circuit designs that incorporate transmission line theory into traditional amplifier design to obtain a larger gain bandwidth product than is realizable by conventional circuits. N stage traveling wave amplifier …
115Rayleigh fading — is a statistical model for the effect of a propagation environment on a radio signal, such as that used by wireless devices.Rayleigh fading models assume that the magnitude of a signal that has passed through such a transmission medium (also… …
116Medium wave — Main article: Medium frequency Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM broadcasting. For Europe the MW band ranges from 526.5 kHz to 1606.5 kHz[1] and in North America an extended MW… …
117Radarhorizont — Der Radiohorizont bezeichnet die Orte, an denen von einem Sender ausgehende direkte (also nicht gebeugte oder reflektierte) Radiowellen genau tangential zur Erdoberfläche verlaufen.[1] Er verläuft meist in größerer Entfernung als der optische… …
