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.
