Product Details Data Sheet

Rogers RO4350B is the most popular Radio Frequency PCB material.

Rogers RO4350B is a hydrocarbon / ceramic laminate with a dielectric constant of 3.48. It meets the requirements of commercial equipment manufacturers for Printed Circuit Boards.

RO4350B is a patented hydrocarbon resin system / ceramic filler reinforced by woven glass cloth. Its electrical properties are very close to PTFE / woven glass cloth material, and its machinability is similar to that of epoxy resin / glass cloth material.


RO4350B can use the standard epoxy / glass cloth processing technology, while providing strictly controlled permittivity and loss at a fraction of the price of traditional microwave materials. There is no need for special through-hole pretreatment or operation procedures like PTFE based microwave materials.


It has the following advantages:

1. Low RF loss

2. Low dielectric constant fluctuation with temperature

3. Low z-axis thermal expansion coefficient

4. Coefficient of expansion in low plate

5. Low permittivity tolerance

6. Stable electrical characteristics at different frequencies

7. Easy to mass production and multi-layer mixing of FR4, with high cost performance


Typical applications

Cellular base station antenna and power amplifier, Microwave point to point connection (P2P), Automotive radar and sensors, Radio frequency identification (RFID) tags,LNB for live satellite
