North America Asia Europe IsoDesign Tools Contact Us RF / Microwave Today’s RF / microwave and millimeter wave 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 dielectric thickness, dielectric constant and dissipation factor, achieving lowest tolerance within a batch as well as batch-to-batch. If any one of these three factors is changed, variations will be seen in the performance of the circuit, such as impedance control, amplitude and phase stability. As frequencies increase, designers are looking to very stable 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 uniform glass reinforcement, helping to improve overall performance and ease of PCB manufacturing TERRAGREEN® (RF/MW) Tg: 200°C Td: 390°C Dk: 3.45 Df: 0.0032 Markets View Details I-TERA® MT40 (RF/MW) Tg: 200°C Td: 360°C Dk: 3.38 / 3.45 / 3.60 / 3.75 Df: 0.0028 - 0.0035 Markets View Details IS680 AG Tg: 200°C Td: 360°C Dk: 3.00 / 3.38 / 3.45 / 3.48 Df: 0.0020 - 0.0029 Markets View Details IS680 Tg: 200°C Td: 360°C Dk: 2.80-3.45 Df: 0.0025-0.0035 Markets View Details ASTRA® MT77 Tg: 200°C Td: 360°C Dk: 3.00 Df: 0.0017 Markets View Details Resources Presentation Article Technical Paper PCB Material Selection for RF, Microwave and Millimeter-wave Design This presentation discusses Printed Circuit Board (PCB) attributes for RF, microwave, millimeter-wave systems through an application example using an advanced automotive safety system.
