　　RO4835T™ 2.5 mil, 3 mil and 4 mil laminates are 3.3 Dk low loss, spread glass reinforced, ceramic thermoset materials that were designed as inner-layers for use in multilayer board designs, and to complement RO4835™ laminates when thinner cores are needed.

　　The world has seen the ongoing evolution of mobile networks, GSM, WCDMA and LTE that has enabled users to grow data consumption at amazing rates and Rogers high frequency materials have played a key role in this market. Antennas, Power Amplifiers, and microwave backhaul radios are needed to create these mobile networks and dielectric constant controlled, low loss materials are the foundation on which this technology is based. High frequency materials are a key enabling technology in the development of the next generation mobile network, 5G which will reach frequencies well into millimeter wave bands where multilayer board designs are prevalent. RO4835T laminates' multiple thickness thin core options are fully compatible with RO4450F™ bondply, the new RO4450T™ thin bondplies, and CU4000™/CU4000 LoPro® foil lamination options. When coupled with RO4835 laminates and RO4000® bonding materials, these material sets provide designers flexibility to achieve requirements related to high multilayer board (MLB) count designs.RO4835T laminates offer the same resistance to oxidation as RO4835 laminates, are low loss, have excellent Dk tolerance, and a tight thickness control for outstanding, repeatable wireless performance. They feature high performance material attributes that provide the optimum blend of price, performance and durability, and can be fabricated using standard epoxy/glass (FR-4) processes.RO4835T laminates utilize RoHS compliant flame-retardant technology for applications requiring UL 94 V-0 certification. These materials conform to the requirements of IPC-4103, slash sheet / 240.

　　方案概述

　　传统微波炉采用磁控管加热，经常烹煮加热不均匀，且有较宽频带电磁泄露。而新型射频微波炉采用全新的射频发射器技术，这项新技术能精确控制辐射的周期、位置和能量。更令人诧异的是，用来发射能量的发射器本身还能感测食物的火候，同时射频信号使用的1MHZ窄频技术根本不会干扰到Wi-Fi。在外形上，与传统微波炉必须造成方形(受限于磁控管的设计原理)不同的是，新型微波炉可以是你想象的任意形状，此外，它的发射器是固态的，使用寿命也会更长。
