A NEW range of high frequency ceramics from Temex, represented by Braemac , offers twice the performance of previous materials for 8–15GHz applications, at no significant extra cost.

Temex E7000 is a high Q material, developed to achieve very low losses at 8–15Ghz. High frequency applications such as 3G base station filters, ultra-stable oscillators and high performance radio links can benefit from this material’s Q.F of 200'000 to 250’000 at 10GHz according to temperature coefficient.

Temex’ previous best material achieved a Q.F of 150’000 at 10GHz.

Resonators based on E7000 series materials offer low losses and high selectivity. There is currently a selection of temperature coefficients available, all manufactured to tight frequency tolerances, ranging from 0 up to +6ppm/°C.

The new material offers a dielectric constant of 24 ±2.

Temex is supporting its new materials with simulation software available from its website. Using a straightforward data entry screen to insert the parameters, designers are offered a recommended device together with a simulation of its performance in the designers system.

The impact of including a spacer can also be evaluated using this tool.
