Rogers RO4730G3 Microwave Printed Circuit Board

Rogers launched the RO4730G3 UL 94 V-0 antenna level laminate to meet current and future higher performance requirements in active antenna arrays, small base stations, 4G base transceiver, Internet of things devices and emerging 5g wireless system applications.

This flame retardant (UL 94V-0) RO4730G3 thermosetting laminate material is a derivative of Rogers' long trusted and popular circuit material for base station antenna applications. It has a low dielectric constant of 3.0, which is preferred by antenna designers, and a z-direction dielectric constant deviation of ± 0.05 at 10 GHz.

RO4730G3 laminate is made of ceramic hydrocarbon material and low loss LoPro? Copper foil. It can provide excellent passive intermodulation performance (usually better than - 160 DBC), which is very attractive for intermodulation sensitive HF antennas. The Printed Circuit Board material of RO4730G3 is 30% lighter than that of PTFE, and its high glass transition temperature (TG) over + 280 ° C makes it compatible with automatic assembly process. In the temperature range of - 55  degree Celsius to + 288  degree Celsius, the coefficient of thermal expansion (CTE) in Z direction is only 30.3 ppm / C, which is conducive to the reliability of electroplated through-hole structure in multilayer circuit assembly. In addition, the lead-free process resistance of the RO4730G3 laminate material can provide better flexural strength than the ro4000jxr material.

The performance of RO4730G3, a new type of laminate for antenna level circuits, is stable with temperature. The material has a coefficient of thermal expansion (CTE) that matches copper and has a very low rate of thermal change in the Z direction of the dielectric constant over the temperature range from - 50 ° C to + 150 ° C (+ 26 ppm / C at 10 GHz). At the same time, the high frequency loss of RO4730G3 is very low, and its loss factor is 0.0023 at 2.5 GHz and 0.0029 at 10 GHz.

RO4730G3 laminate material provides a practical and cost-effective material solution for current 4G, IOT wireless devices, and active antenna arrays and PCB antennas in future 5g wireless devices. Combined with the right materials, ro4730g3 material can provide the best combination of price, performance and durability.

It is compatible with the conventional rf-4700 laminate and has no special requirements for high-temperature soldering of the RF-4700 laminate. This material is an economical alternative to PTFE antenna material and can help designers achieve high cost performance.

The resin system of RO4700 dielectric material has the necessary properties to achieve ideal antenna performance. The coefficient of thermal expansion (CTE) of X and Y axes is similar to that of copper foil. Good fit of thermal expansion coefficient reduces the stress in PCB antenna. The glass transition temperature of RO4700 material is higher than 280 ° C (536 ° f), which makes the z-axis CTE lower, thus ensuring excellent through-hole plating reliability.

The loss of RO4730G3 is higher than that of RO4730jxr due to the addition of flame retardant filler. At 3.5GHz frequency, the loss of RO4730G3 with 30.7mil thickness increases by 0.0009db/cm compared with that of RO4730jxr at 3.5GHz frequency.

Radio Frequency (RF) microwave PCB application

RF Microwaves PCBs (printed circuit board) are used in various of fields, Such as Consumer Electronics / Military/Space / High power / Medical / Automotive / Industrial ect.

RF/Microwave PCB application

PCB printed circuit boards with radio frequency(RF PCBs) are an increasingly used technique within the PCB industry.

--RF PCB with a high frequency with works above 5G.

--Microwave PCB with works above 5 GHz radio frequency.

RF-pcb’s are used in different applications such as remote controls(wireless controls)security,smartphones,sensors etc.

New technologies make more and more use of these RF applications.

This asks for a manufacturing according to high quality standards and choosing the right RF materials depending on the application.

It is important that one knows the properties of the various materials.Choosing the right material is perhaps the most critical decision in the production process of the RF PCB.
