High
Frequency PCB Rogers 30mil 0.762mm RO4350B Double Sided RF Circuit Board for
LNCs
(Printed
Circuit Boards are custom-made products, the picture and parameters shown are
just for reference)
RO4350B hydrocarbon ceramic laminates are designed to offer superiorhigh frequency
performanceand low cost circuit fabrication. The selection of laminates
typically available to designers is significantly reduced once operational
frequencies increase to 500 MHz and above. Low dielectric loss allows RO4350B material to be used in many
applications where higher operating frequencies limit the use of conventionalcircuit board materials.
The
temperature coefficient of dielectric constantis among the lowest of any circuit
board material, and the dielectric constant is stable over a broad frequency
range. RO4350B material's thermal coefficient of expansion(CTE) provides
several key benefits to the PCB designers. The expansion coefficient of RO4350B
is similar to that of copper which allows the material to exhibit excellent
dimensional stability, a property needed formixed dielectric multi-layer
boardsconstructions. The low Z-axis CTE of RO4350B provides reliable plated
through-hole quality, even in severe thermal shock applications. RO4350B
material has aTg of >280Cso its expansion characteristics remain stable
over the entire range of PCB processing temperatures.

High-frequency PCBs are available in the 500MHz - 2GHz frequency range
and are ideal for high-speed designs as well as radio frequency (RF),
microwave and mobile applications. In high frequency PCB manufacturing,
layers must be aligned.
