High Frequency PCB Rogers 60mil 1.524mm RO4350B Double Sided RF
Circuit Board Patch Antenna PCB
(Printed Circuit Boards are custom-made products, the picture and
parameters shown are just for reference)
RO4350B hydrocarbon ceramic laminates are designed to offer
superior high frequency performance and low cost circuit
fabrication. The selection of laminates typically available to
designers is significantly reduced once operational frequencies
increase to 500 MHz and above.
RO4350B material possesses the properties needed by designers of RF
microwave circuits and matching networks and controlled impedance
transmission lines. Low dielectric loss allows RO4350B material to
be used in many applications where higher operating frequencies
limit the use of conventional circuit board materials.
The temperature coefficient of dielectric constant is 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 for mixed dielectric multi-layer boards constructions.
The low Z-axis CTE of RO4350B provides reliable plated through-hole
quality, even in severe thermal shock applications. RO4350B
material has a Tg of >280C so its expansion characteristics
remain stable over the entire range of PCB processing temperatures.
