The problem is range are large and the calculation will vary depends on where your PCB is in the given range. Material selection is an important part of Mil/Aero PCB design and manufacturing to ensure superior reliability and performance in the most extreme conditions and critical applications. When signal attenuation is important, use a low-loss high-speed material. The frequency for RF board is normally between 300MHz ~ 3GHz, or much bigger, so normally FR4 board cannot meet the requirements, so we need to use special material to achieve the high frequency and we named this kind of boards as RF boards. The electrical characteristics of the PCB used to physically mount and connect the circuit components in a high frequency RF product can have a significant impact on the performance of that product. Most of these are handheld wireless devices for medical, industrial, and communications applications. Most PCB material selection starts with the material’s dielectric constant, which is the energy storing capacity of the material.

The spacing between two vias should never be more than one-twentieth of the wavelength of the RF signals. When determining the choice of substrate material, a designer must have a strong understanding of the environmental conditions, which the PCB assembly can withstand. PTFE with microglass fiber or woven glass is the go-to material when quality is more important than price. The interconnects are most often created with stripline and microstrip transmission lines, as well as vertical coaxial transmission lines created with plated through hole patterns. If your PCB design includes only two layer, the top layer should include the power stage, RF signal lines and RF components. A suitable low-loss material. For most PCB materials, however, the CTE is typically much higher in the z-axis (t he thickness) t han in the x or y axes. 2) The length of the lines that carry RF/Microwave signals is a very important issue. Founded in 1980, Cirexx International, Inc. Microwave and RF PCB Materials RF and microwave PCBs are typically built using advanced composites with very specific characteristics for dielectric constant (Er), loss tangent, and co-efficient of thermal expansion (CTE). Most PCB plates are made of a material known as FR-4 (Flame Retardant level 4), which is a glass fiber/epoxy composite with copper foil laminated on one or both sides. This includes the selection of the RF PCB material, discussion of the CAD to CAM RF design documentation, and how to evaluate PCB fabricators for RF fabrication quality.

Since late in the 90’s, Cimulec worked in this field and is able to provide innovative solutions for special and complex RF / Microwave bare boards : - standard multilayer or sequential build-up up to 20 layers (more if requested), - RF materials such as thermoset, PTFE , … • RF & Microwave Design Techniques for PCBs – Lawrence M. So far, I know some like Teflon, PPL, PVC, and ABS. List of base materials grouped by Df, showing preferred status and leadtime. In an RF or microwave circuit, the value of the dielectric constant will impact the PCB’s trace sizes and therefore the size of the PCB. The PCB serves as the physical foundation upon which your electrical components, conductive traces, pads, and other features will reside. PNC Inc. • Minimizing Vias in RF Path Minimizes Breaks in Ground Plane(s)- - Minimizes Inductance. RF circuit boards are incredibly complex with a dizzying range of options. We sell PTFE fabric to customers who use these material for laminate-release sheets, food conveyor belts, electrical insulation and industrial processing purposes. rf pcb material
