High Frequency PCB Rogers *0mil 1.**4mm RO***0B Double Sided RF Circuit Board Patch Antenna PCB

RO***0B 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 **0 MHz and above.  
 
RO***0B material possesses the properties needed by designers of RF microwave circuits and matching networks and controlled impedance transmission lines. Low dielectric loss allows RO***0B 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.
 
RO***0B material's thermal coefficient of expansion(CTE) provides several key benefits to the PCB designers. The expansion coefficient of RO***0B 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 RO***0B provides reliable plated through-hole quality, even in severe thermal shock applications. RO***0B material has a Tg of >**0C so its expansion characteristics remain stable over the entire range of PCB processing temperatures.
