High Frequency PCB Double Sided RF PCB Repeater PA
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
RO4003C 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.
Designers of RF microwave circuits, matching networks, and controlled impedance transmission lines can rely on the features of RO4003C material. Higher operating frequencies prevent the use of standard circuit board materials in many applications, while low dielectric loss enables RO4003C material to be employed in those applications.
The dielectric constant is consistent across a wide frequency range and has one of the lowest temperature coefficients of any circuit board material. The thermal coefficient of expansion (CTE) of the RO4003C material offers the PCB designers a number of significant advantages. Due to its identical expansion coefficient to that of copper, RO4003C exhibits high dimensional stability, a quality required for the creation of mixed dielectric multi-layer boards.
The low Z-axis CTE of RO4003C provides reliable plated through-hole quality, even in severe thermal shock applications. RO4003C material has a Tg of >280C so its expansion characteristics remain stable over the entire range of PCB processing temperatures.
