Effects of Polymer Material Variations on High Frequency Dielectric Properties
نویسنده
چکیده
In high frequency signal packaging, the plastic dielectric material takes on an increasingly important role in the performance of the signal transmission. Variations within the plastic can occur as a result of a number of manufacturing and environmental processes. These variations can be sufficient to change the dielectric properties. The extent of change to the dielectric properties of polymer materials as a result of controlled variations to major filler additives, moisture and temperature has been investigated. The combined effects of moisture and temperature can cause changes to the dielectric constant of certain materials by more than 30 %.

متن کاملSecond Harmonic Reduction of Traveling Wave Tube Amplifier Using Ferrite Material
Traveling Wave Tubes (TWTs) consist of different elements. The most important element of TWT is the RF circuit. RF circuits in helix TWTs need a dielectric support to hold the helix; this support also has an effect in electromagnetic properties of RF circuits. A novel dielectric support is proposed to reduce the second harmonic of helix TWTs. The dielectric support in this structure consists of...
