High Frequency PCB Rogers 60mil 1.524mm RO4350B Double Sided RF Circuit Board Patch Antenna PCB

The RO4350B material, with its superior high-frequency performance and low-cost circuit fabrication, is well-suited for various applications in RF microwave circuits. Here are some key points based on the information provided:

1. High Frequency Performance: RO4350B is specifically designed to excel at high frequencies, making it suitable for applications where operational frequencies increase to 500 MHz and above.
2. Dielectric Loss: RO4350B exhibits low dielectric loss, allowing for efficient signal transmission and reduced signal attenuation at higher operating frequencies. This characteristic enables its use in applications where conventional circuit board materials may not be suitable.
3. Stable Dielectric Constant: The dielectric constant of RO4350B is stable over a broad frequency range. Additionally, it has one of the lowest temperature coefficients of dielectric constant among circuit board materials. This stability ensures consistent performance in varying temperature conditions.
4. Dimensional Stability: The thermal coefficient of expansion (CTE) of RO4350B is similar to that of copper. This similarity in expansion coefficients enhances the material's dimensional stability, which is crucial for mixed dielectric multi-layer board constructions.
5. Plated Through-Hole Quality: The low Z-axis CTE of RO4350B contributes to reliable plated through-hole quality, even in severe thermal shock applications. This ensures the integrity of connections and enhances the overall reliability of the PCB.
6. Tg Stability: RO4350B has a glass transition temperature (Tg) of >280°C, indicating that it remains stable and retains its desirable characteristics over the entire range of PCB processing temperatures.

Based on these properties, typical applications for RO4350B PCBs include automotive radar and sensors, cellular base station antennas, direct broadcast satellites, low noise blocks, power amplifiers, and RFID systems.

Please note that specific parameters and designs for custom-made RO4350B PCBs may vary depending on the manufacturer and the specific requirements of the project.
