How Rogers 4730 PCBs Compare to Other High-Frequency Laminated Substrates? Rogers 4730 PCBs are just one type of high-frequency laminated substrate available in the market. Here's how they compare to some other commonly used high-frequency laminated substrates: 1. FR-4: FR-4 is a commonly used substrate material for PCBs. It has a low cost, high mechanical strength, and a dielectric constant of around 4. However, its dielectric loss is relatively high, making it unsuitable for high-frequency applications. 2. Rogers 4003C: Rogers 4003C is a popular high-frequency laminated substrate that has a dielectric constant of 3.38 and a low dissipation factor of 0.0027 at 10 GHz. Compared to Rogers 4730, it has a higher dielectric constant, but it is also less expensive. 3. Arlon AD450: Arlon AD450 is another high-frequency laminated substrate that has a dielectric constant of 4.5 and a low dissipation factor of 0.0023 at 10 GHz. It is often used in RF and microwave applications. Compared to these substrates, Rogers 4730 PCBs have a lower dielectric constant of 2.8, making them suitable for even higher frequency applications. They also have a lower dissipation factor of 0.0027 at 10 GHz, which means they lose less signal power as it travels through the substrate. Additionally, Rogers 4730 PCBs have a lower coefficient of thermal expansion (CTE) of 9 ppm/°C compared to FR-4, which makes them more stable over a wider temperature range. In terms of cost, Rogers 4730 PCBs are generally more expensive than FR-4, but less expensive than some other high-performance laminates like Rogers 4003C. Overall, Rogers 4730 PCBs offer a unique combination of low dielectric constant, low dissipation factor, and low CTE, making them ideal for high-frequency and high-speed applications where signal integrity is critical.
