Stripline devices embedded in RT-duroid laminates are widely used for high-frequency circuits due to their excellent dielectric and thermal properties. Calculating the correct line width for a specific characteristic impedance (Z0Z_0Z0​) is essential for optimal signal integrity and impedance matching. 1. Design Parameters The characteristic impedance of a center stripline is influenced by several factors: Substrate Thickness...

Rogers laminates, including popular materials like RT-duroid® 5870 and 5880, are well-regarded for their low outgassing properties, making them suitable for use in space, vacuum, and other environments where minimal material outgassing is critical. 1. Understanding Outgassing Outgassing is the release of volatile compounds from a material when exposed to vacuum or high-temperature environments. Excessive outgassing...

RT-duroid 5870 laminates are high-performance microwave and radio frequency (RF) circuit materials manufactured by Rogers Corporation. These laminates are widely used in high-frequency applications due to their low dielectric constant, low loss tangent, and excellent stability under various environmental conditions. 1. Key Features of RT-duroid 5870 Low Dielectric Constant (ϵr=2.33\epsilon_r = 2.33ϵr​=2.33): Minimizes signal delay and...

RT-duroid® laminates are high-performance PTFE-based composite materials manufactured by Rogers Corporation. These laminates are primarily used in RF, microwave, and high-frequency applications due to their exceptional dielectric properties, thermal stability, and chemical resistance. 1. Composition of RT-duroid Composites Base Material: Polytetrafluoroethylene (PTFE): Provides a low-loss, stable dielectric medium with excellent high-frequency performance. Reinforcements: Glass Microfibers: Enhance mechanical stability...

Polytetrafluoroethylene (PTFE)-based composites, such as RT-duroid laminates, are widely used due to their exceptional properties. However, working with PTFE composite materials requires awareness of safety precautions during handling, machining, and disposal. 1. General Safety Considerations Inert Material Properties: PTFE is chemically inert and stable under normal conditions, making it non-toxic in its solid state. However, machining or...

When Rogers high-frequency circuit boards, such as RT-duroid laminates, carry direct current (DC) or radio frequency (RF) current, the temperature rise depends on factors such as conductor resistance, material properties, current flow, and thermal management. 1. Factors Influencing Temperature Rise Conductor Properties: Thickness and Width: Wider and thicker traces reduce resistance. Material Conductivity: High-conductivity materials like copper lower resistive...

The nearly isotropic dielectric constant (ϵr\epsilon_rϵr​) of RT-duroid® 5870 – 5880 laminates, attributed to their glass microfiber-reinforced PTFE composition, offers several key benefits for high-frequency applications. Here’s why this property is advantageous: 1. Consistent Signal Performance in All Directions Isotropy Defined: An isotropic dielectric constant means ϵr\epsilon_rϵr​ remains the same regardless of the direction of signal propagation....
