Hello Everyone,
Today we’re talk about RO3003 high frequency PCBs.
RO3003 high frequency circuit laminates are ceramic-filled PTFE composites intended for using in commercial microwave and RF applications. Its obvious characteristic is that the electrical performance is exceptional and the mechanical property is stable and consistent. This allows our designers to develop multi-layer board design feeling free and free, without encountering warpage or reliability problems.
Let’s see some more features and applications.
Firstly, low dielectric loss, DF=0.001, it can be used in applications up to 77 GHz.
Secondly, Stable dielectric constant versus temperature and frequency, it’s ideal material for band pass filters, microstrip patch antennas, and voltage controlled oscillators.
Thirdly, excellent mechanical properties versus temperature, it’s reliable stripline and multi-layer board constructions.
Fourthly, Uniform mechanical properties, it’s suitable for use with epoxy glass multi-layer board hybrid designs.
Fifthly, low in-plane expansion coefficient matches to copper, it allows for more reliable surface mounted assemblies; ideal for applications sensitive to temperature change and exhibit excellent dimensional stability.
