Rogers 4350 vs FR4

Single chip RF device greatly facilitates the application in the field of wireless communication in a certain range. A complete wireless communication link can be formed by using appropriate microcontroller and antenna combined with this transceiver. They can be integrated on a small PCB and applied to many fields, such as wireless digital audio, digital video data transmission system, wireless remote control and telemetry system, wireless data acquisition system, wireless network and wireless security system.

If the analog circuit (RF PCB) and the digital circuit (microcontroller PCB) work separately, they may work well, but once they are placed on the same PCB, they cannot work together with the same power supply. This is the difference between Rogers ro4350b and FR4.

Ro4350b developed by Rogers, an internationally famous advanced PCB material manufacturer, meets the stringent requirements of commercial equipment manufacturers for PCB and has strong market competitiveness. Ro4350b not only has good high-frequency performance, low RF loss and excellent electrical characteristics, but also has other characteristics such as low production cost of ro4350b PCB, multi-layer hybrid pressing of ro4350b and FR4, and has strong market competitiveness.

Ro4350b PCB is in the range of - 50 ~ 150 degrees, and the change of ro4350b dielectric constant is 4‰, which lays a solid foundation for the temperature characteristics of communication equipment.

Cost performance of ro4350b. R & D RF engineers hope that good electrical performance is good and stable; From the perspective of the company's products, the cheaper the things, the better. And now the miniaturization of communication equipment requires more and more RF circuits and digital circuits can not be designed without mixing. So the contradiction appeared. How should ro4350b and FR4 choose? Ro4350b is a high-frequency PCB material. Its high-frequency electrical characteristics are better than FR4, but its price is also higher than FR4.

It can be selected in this way. For the hybrid PCB of ro4350b and FR4, only the RF device part of the equipment needs to be placed on the side of ro4350b and the digital device part needs to be placed on the side of FR4. Ro4350b PCB stack-up is as follows:

Ro4350b PCB stack-up

Some key characteristics of ro4350b PCB are analyzed. From the above analysis, it can be seen that ro4350b PCB not only has good high-frequency performance, low RF loss and excellent electrical characteristics, but also has other excellent characteristics such as low PCB production cost and can be mixed with FR4 multilayer. It is a high cost-effective PCB RF material.
