Continuous integration plus self-shielding-5G RF focus [Copy link]

5G has brought about major changes in the communications industry. The number of communication frequency bands has been growing rapidly since the 4G era. As a core component of mobile phone communication functions, the RF front end will benefit directly. In the mobile phone field, although mobile phone sales are expected to decline by 10% this year, Qorvo believes that the value growth of 5G mobile phone RF end by $5-7 can offset the negative impact of the decline in mobile phone sales.

In the RF front end, the generation of EMI (electromagnetic interference) and RFI (radio frequency interference) is a common problem, and as more and more components are integrated into the RF front end module, this phenomenon will become more common. At present, the industry generally uses an external mechanical shielding cover to shield the RF module, that is, embedded in a metal shell to protect the module from the influence of external electromagnetic fields. However, this practice may cause a decrease in sensitivity and an increase in harmonics, causing damage to the equipment and bringing many design risks.

To address the above issues, Qorvo developed a self-shielding module, which adds a layer of self-shielding metal coating on the surface of the module, which can reduce the surface current by 100 times. This is equivalent to its RF front-end module having a built-in shielding cover, and there is no need to worry about the placement of the mechanical shielding cover.

The above content comes from " Qorvo talks about 5G RF: continuous integration and self-shielding will become a major trend. " Do you think this is the difficulty and trend in the future?

Embedded in metal shell. I don't know how embedded it is.

I still know something about the shield

Yeah, I really don't know how to add a shielding cover.

Can it be understood that like the CPU, the surface is metal, so the self-shielding technology is good? Because he mentioned that it is used in high-end machines, so cheap products still use shielding covers, just like the previous mobile phones or cheaper ones still use shielding covers
