In order to grab 5G orders, Samsung pushes 8nm RF chip manufacturing process

Samsung Electronics announced the development of 8nm radio frequency (RF) chip process technology with a high profile last week, hoping to seize the foundry orders in the 5G field.

It is reported that Samsung has developed a unique 8nm RF dedicated architecture, called RFextremeFET (RFeFET?), which can significantly improve RF characteristics while using less power.

Compared with 14nm RF, Samsung's RFeFET supplements digital PPA scaling and at the same time restores analog/RF scaling, thus realizing a high-performance 5G platform. In addition, the new 8nm RF chip can increase efficiency by 35% and reduce the area by 35%.

According to news such as Newsis, Samsung plans to use 8nm RF wafer foundry technology services to rush into the 5G field.

According to reports, Samsung's cutting-edge foundry technology is expected to provide "single-chip solutions" specifically for 5G communications that support multi-channel and multi-antenna chip designs. Samsung's 8nm RF platform expansion is expected to extend the company's leading position in the 5G semiconductor market from sub-6GHz to millimeter-wave applications.

IT Home Science: Radio Frequency (Radio Frequency) and literal translation from English. Among them, the earliest application of radiofrequency is Radio-radio broadcasting (FM/AM), which is still the most classic application of radiofrequency technology and even the radio field so far.

Radiofrequency is abbreviated as RF. Radiofrequency is a kind of high-frequency alternating electromagnetic wave. It is the abbreviation of Radio Frequency, which means the electromagnetic frequency that can radiate into space. The frequency range is between 300KHz and 300GHz.

The alternating current that changes less than 1,000 times per second is called a low-frequency current, and the one that changes more than 10,000 times is called a high-frequency current. Radiofrequency is such a high-frequency current. High frequency (greater than 10K); radio frequency (300K-300G) is the higher frequency band of high frequency; microwave frequency band (300M-300G) is the higher frequency band of radiofrequency.

A radio frequency chip refers to an electronic component that converts radio signal communication into a certain radio signal waveform and sends it out through antenna resonance, that is, a chip that can convert radio frequency signals and digital signals. It includes an RF transceiver, power amplifier (PA), low noise amplifier (LNA), filter, radio frequency switch, antenna tuning switch, etc.

As we all know, the most important core components in mobile terminals such as mobile phones are radio frequency chips and baseband chips. The RF chip is responsible for RF transceiver, frequency synthesis, and power amplification; the baseband chip is responsible for signal processing and protocol processing.

Radiofrequency: generally the part of information sending and receiving;

Baseband: generally the part of information processing;

Power management: It is generally a power-saving part, which is quite important for mobile phones;

Peripherals: generally include LCD, keyboard, shell, etc.;

Software: generally includes systems, drivers, middleware, and applications.
