RO4830 PCB 2-layer 5mil PCB

Shipped: 23rd-May-2024  

1. Introduction of RO4830
Rogers RO4830 high frequency laminates are thermoset materials that serve as a reliable, lower cost alternative to conventional PTFE based laminates. RO4830 laminates have a slightly higher dielectric constant of 3.2 at 77GHz, versus PTFE-woven glass laminates.
LoPro? reverse treated copper foil cladding contributes to RO4830 laminates' excellent insertion loss at 77GHZ of 2.2 db per inch.

RO4830 thermoset laminates are well suited for price-sensitive millimeter wave applications, such as 76-81 GHz automotive radar sensors. RO4830 laminates can be fabricated using standard FR-4 processes and are intended for the cap layer on FR-4 multi-layer board designs commonly used in 76-81 GHz automotive radar sensor PCB applications.
2. Features
- Dielectric Constant of DK 3.24 at 77GHz/23°C
- Dissipation Factor of 0.0033 at 10GHz/23°C
- Excellent Thermal Coefficient of Dielectric Constant -30 ppm/°C
- Excellent insertion loss of 2.2 db/in at 77 GHz
