Rogers RT/duroid
5880 RF PCB with 10mil, 20mil, 31mil and 62mil Coating Immersion Gold,
Immersion Silver, Immersion Tin and HASL
(PCB's are custom-made products, the picture
and parameters shown are just for reference)
There is an high frequency PCB built on RT/duroid 5880 laminates.
RT/duroid 5880 is one of Rogers’ glass
microfiber reinforced PTFE composite which is designed for exacting stripline
and microstrip circuit applications.
Why do we use RT/duroid 5880?
Firstly, the randomly oriented microfibers
result in exceptional dielectric constant uniformity.
Secondly, the dielectric constant of RT/duroid
5880 laminates is uniform from panel to panel and is constant over a wide
frequency range.
Thirdly, its low dissipation factor extends the
usefulness of RT/duroid 5880 laminates to Ku-band and above. It’s as low as
0.0004 when 1 MHz and 0.0009 when 10 GHz.
Fourthly, designed for exacting stripline and
microstrip circuit applications

RT/duroid 5880 material can be made in double
layer board, multilayer board and hybrid types. The double sided boards are
available in a variety of thicknesses, such as 10mil, 20mil, 31mil and 62mil.
The typical applications are microstrip
and stripline circuits, commercial airline broadband antenna，radar systems, millimeter wave applications, point to point
digital radio antenna etc.
The basic colour of RT/duroid 5880 PCB
is black.
RT/duroid 5880 PCB also has the properties of
low water absorption, excellent chemical resistance etc.
