1. Introduction of F4BM300
Rogers RO4830 high-frequency laminates are thermoset materials offering a reliable and affordable alternative to traditional PTFE-based laminates. With a dielectric constant of 3.2 at 77 GHz, RO4830 laminates surpass PTFE-woven glass options. The use of LoPro reverse treated copper foil cladding ensures excellent insertion loss performance of just 2.2 dB per inch at 77 GHz.

|
|
|
Designed for price-sensitive millimeter wave applications, such as 76-81 GHz automotive radar sensors, RO4830 laminates can be fabricated with standard FR-4 processes. They are specifically intended for the cap layer in FR-4 multi-layer board designs, making them ideal for automotive radar sensor PCB applications. |
