CGH-500

CGH-500

The Copper-clad laminated circuit board using flouroplastic impregnated glass fabric containing inorganic filler as the dielectric.
Obtaining characteristics of fluoroplastic, it also has lower water absorbency than resins.

Use

All mobile communication systems/Power amplifier for broadcast transmission and reception

Operating temperature range

-60°C to +220°C

Structure

CGH-500 Structure

Characteristics

●Compare to a general-purpose circuit board such as glass epoxy circuit board, this product provides low dielectric dissipation circuit even both have same level of permittivity.
●Low loss circuit can be obtained.
●It has 3.5 dielectric constant.

*The dielectric constant is assumed to be 3.50. However, the dielectric constant varies with varying thickness.
*The tolerance of the dielectric constant is assumed to be ±0.12 for any one variety.

*As a standard we have used ½ oz. electrolytic copper foil on both sides. For other thicknesses of electrolytic copper foil, copper foil on one side, rolled copper foil, or in the case where other special measurements are necessary, please seek a special consultation from us directly.
