Isola to show unique RF and microwave circuit materials
At the European Microwave Exhibition in London, Isola will be providing guidance on the best use of its advanced circuit materials for printed circuit boards. Isola’s material experts and sales professionals, including new addition Jim Francey, will welcome visitors to learn about the optimum circuit material choices for applications in variety of markets.
Isela将重点介绍其用于高速数字（HSD）和RF/Microwave电路的独特电路材料，包括在具有挑战性的汽车和军事雷达应用中提供“设计自由”的材料，例如Astra®MT77。它在高温和功率水平下提供出色的热稳定性，低介电常数（DK）为10 GHz时为3.00。它的低损失用10 GHz时的耗散因子（DF）表示为0.0017。在RF /微波频率下损失较低的另一种电路材料，I-TERA®MT40（RF / MW），DK值在10 GHz时为3.38 / 3.45 / 3.60或3.75，在10 GHz和DF时为0.0028。Astra®MT77和I-TERA®MT40非常适合新兴毫米波（MMWAVE）电路应用，例如5G无线网络和汽车雷达。两者都是FR-4工艺兼容，以便于电路制造。
的词rcuit fabricators seeking environmentally safe solutions, Isola will show its standard TerraGreen® and higher-frequency TerraGreen® 400G (RF/MW) circuit materials. Both are halogen-free circuit materials, with little or no halogens, such as chlorine or bromine, which can form hazardous materials if a PCB is overheated or on fire. Especially for RF/microwave applications, TerraGreen® (RF/MW) circuit materials feature a stable Dk with temperature, holding to 3.45 at 2, 5, and 10 GHz and temperatures from -55 to +125°C with low Df of 0.0032 at 2, 5, and 10 GHz. The halogen-free RF/microwave circuit materials are RoHS-compliant for lead-free processes and can be used in mmWave circuits to 110 GHz.
In addition, at the European Microwave Exhibition, Isola’s representatives will explain how IS680/IS680AG laminates provide sound starting points for RF/microwave circuits in both commercial and military/aerospace RF/microwave applications. Available with a wide range of copper weights the laminates exhibit Dk values of typically 2.80 to 3.45 with Df from 0.0025 to 0.0035 from 2 to 10 GHz and maintain stable Dk and Df from -55 to +125°C.
