Unisoc unveils 5G RF solution to bring more design space to thin phones

Unisoc, a Chinese fabless semiconductor company, today introduced its 5G RF front-end solution, a modular design that reduces channel loss by 15% over the industry average and reduces the size by 20%, enabling more design space for thin and slim smartphones.
Compared to most solutions, the Unisoc 5G RF front-end solution is a complete solution, offering a full range of active chips and devices for the entire RF front-end.

Unisoc said the overall lead time from customer reference design through device selection, matching and debugging, and volume production tracking is 20% shorter than the industry average, significantly reducing product development time and simplifying development for OEMs.


Unisoc 5G RF shortens the response time from 5us in 4G to 1us, so that the terminal signal remains stable even on a speeding high-speed train, according to the company.
At the same power, Unisoc power amplifiers consume 4 percent less power than competing products - far more than the industry average. They operate 10 minutes longer at maximum power transmission and 20 minutes longer at normal power transmission.

Unisoc 5G RF front-end solutions support the world's leading 5G frequency bands, including N77, N78, N79, N41, N28, and N1, meeting the diverse needs of the global market for 5G high, mid and low bands.

The key driver of domestic localization is Huawei not academics or think tank

Huawei had done nothing for decades they live in dream word of globalization and they bought hook and sink the western propaganda of "free trade", " comparative advantage" etc, etc. They lacked vision and foresight.

If it not for the effort of Chinese academies and research center where China would be today! Unlike in the 50's China is better prepared now to face the tech embargo. Research takes decade But at least the academies already did the ground work

Now they realized their fatal mistake, they adopt 180 approach. Willing to start from scratch with older technology shows their path of redemption or repentance mindset.
They have the most incentives due to the status of biggest target.
Academics cant bring it the industrial scale unless key industry players want it badly.

That's why I don't pay attention to academic folks suggestion because they are not the real driver.

Yeah! Exactly!

That's why I can never stop talking about Huawei.

I do not believe anyone in China purchase SMEE 90nm litho equipment for mass production until Huawei comes along. I could be wrong. But I don't recall anyone buy it.

You said it brother.

That's how is it often works. We just need that one break.

Once that door opens, got to make the most of it.

(That's why I feel this game is rigged! Once that door is opened, then CCP will play the role of the rich uncle, supplying endless funds and technical support via their insolvent think tanks and academic enterprises, like long march, to ensure Huawei and SMIC and SMEE and et al, will all succeed and be one big happy family under heaven.)

Hi WTAN,

Are you referring this new equipment as a replacement for the already paid EUVL machine that had accidentally caught fire (ahem!!! sabotage by the American)?

Its not the EUV.
I believe that SMIC was already planning to begin production of the N+1 Chip and thus ordered some new 7nm Semiconductor Machinery.
They probably already got the equipment before they were hit with sanctions.
Thats why SMIC is confident in moving ahead with its plans for the N+1 Chip. Of course its stockpile of parts helps as well.
SMIC can probably build a De-Americanised FAB using the SMEE 28nm DUV and Japanese Equipment to produce its N+1 and N+2.
That might be a interim plan while waiting for the 100% localised 14nm and 7nm Production line to be ready.

Huawei just sold it's Honor brand cellphone division for $15billion.

Good! Now just focus on the essential stuffs.

Each Tesla car or electrical car uses hundred of analog chips for control.

Those kind of chips use older technology fab and Huawei should branch out into that area. Not just telecom.

Huawei still did better than other Chinese companies like Xiaomi or BBK. They at least design their own chips and has an EDA capability.

Huawei design their own chips but I don't know if they designed their own core or not.
I thought they used ARM cores and GPUs and added some of their own logic around that.
But there are people with the ability to design CPU cores in China.
