Isola RF Microwave

The commercial wireless markets are highly competitive and have an ever increasing demand for more speed and bandwidth. Today’s designers are challenged more than ever with the task of achieving an optimal balance between cost and performance when selecting base materials.

Key factors include precise control of the tolerance adherence on the dielectric constant and dissipation factor, dielectric thickness and batch to batch product consistency. It has been well documented that to achieve controlled impedance and consistent electrical performance along the lines of amplitude and phase response RF high frequency designs require extremely precise controls on line widths (inductance), dielectric constant (resistance) and dielectric thickness (capacitance). If any one of these three factors is changed variations will be seen in impedance. As data transfer rates increase on the high speed digital frontier designers are looking to controlled dielectric materials as a means of achieving optimal signal performance. This would include the designers also paying closer attention to the selection of copper foils such as VLP-2 (very low profile 2 micron), as well as woven glass styles such as square weave or spread glass styles that would also help improve performance.
