Welcome to our product blog, where we are excited to introduce RO4350B, a game-changing microwave laminate developed by Rogers. Prepare to embark on a journey into the world of high-frequency applications, as we delve into the exceptional features, benefits, applications, and considerations of RO4350B. This revolutionary laminate has captured the hearts of engineers and designers globally, redefining what's possible in the realm of RF technology.
Unmatched Electrical Performance:
RO4350B materials combine the best aspects of PTFE/woven glass
laminates and epoxy/glass composites, resulting in outstanding
electrical performance. With precise control over its dielectric
constant (Dk) at 3.48 +/- 0.05 (10GHz) and an impressively low
dissipation factor of 0.0037 at the same frequency, RO4350B ensures
unparalleled signal integrity. This makes it the go-to choice for
applications demanding higher operating frequencies and broad
bandwidth capabilities.
Stability and Reliability:
RO4350B stands out for its remarkable stability across diverse
frequencies, guaranteeing controlled impedance transmission lines
and enabling engineers to design repeatable filters. Its low
thermal coefficient of dielectric constant and superior dimensional
stability further enhance reliability, even in challenging
operating conditions.
Versatile and Cost-Effective:
RO4350B laminates offer the best of both worlds, combining superior
performance with cost-effectiveness. Embracing conventional glass
epoxy fabrication techniques, RO4350B eliminates the need for
specialized through-hole treatments or cumbersome handling
procedures associated with PTFE-based materials. This simplifies
the manufacturing process and significantly reduces costs, making
RO4350B an economically viable solution for high-power RF designs
and active devices.
Robust Construction Details:
RO4350B excels in 2-layer rigid PCB configurations, embodying a
robust construction that ensures optimal electrical performance and
structural integrity. With copper layers measuring 35 μm on both
sides and a core thickness of 0.254 mm (10mil), this configuration
strikes the perfect balance between durability and flexibility. The
finished board thickness of 0.32mm, complemented by a 1oz (1.4
mils) outer layer copper weight, guarantees resilience and
adaptability in equal measure.
Diverse Applications:
RO4350B finds its place across an array of industries and
technological domains. Its exceptional properties make it an ideal
choice for cellular base station antennas, power amplifiers, RF
identification tags, automotive radar systems, and direct broadcast
satellite LNBs. With reliability, stability, and a competitive
price point, RO4350B empowers engineers to explore the boundaries
of high-frequency designs, driving innovation across multiple
sectors.
Shortcomings to Consider:
While RO4350B offers impressive performance and advantages, it's
important to consider a few limitations. Firstly, the thermal
conductivity of 0.69 W/m/°K may not be as high as some specialized
materials, which may impact heat dissipation in certain high-power
applications. Additionally, the coefficient of thermal expansion
(CTE) values of 10ppm/°C (X-axis), 12ppm/°C (Y-axis), and 32ppm/°C
(Z-axis) could pose challenges in designs requiring precise
dimensional stability across a wide temperature range.
Conclusion:
RO4350B from Rogers is revolutionizing the field of microwave
laminates, delivering exceptional electrical performance,
stability, and cost-effectiveness. With precise control over its
dielectric constant, low loss characteristics, and ease of
manufacturing, RO4350B opens up a world of possibilities for
high-frequency applications across various industries. While
considering factors such as thermal conductivity and CTE, RO4350B
remains a powerful choice for engineers seeking unmatched
performance and reliability. Experience the power of advanced
microwave laminates with RO4350B and unlock the true potential of
your RF designs. Contact us today to embark on a journey of
limitless possibilities with RO4350B and elevate your projects to
extraordinary heights.
