After learning more about what Shi Yongxin said, Sheng Huainan knew the general situation.

Now, the Shangsha R&D Center has encountered some R&D problems!

Shangsha Mate 2 is a breakthrough product.

Generally speaking, for some breakthrough products, the preparation time of the product is relatively long, and generally speaking, it needs to go through the evolution process of theoretical research, technical research, technology molding, technology productization, mass production, and then to large-scale production, efficiency improvement and cost reduction.

Now, thanks to Sheng Huainan's involvement, it can be shortened to a large extent from the technical forming.

However, there is also a problem with this, that is, many Mate 1 R&D technologies cannot be continuously iterated!

In R&D, in order to match the commercial window of opportunity, it is necessary to further subdivide the time window into different stages and decompose it into product details at different points in time, specifically to quarters or even months or days.

Now the timeline can't go on!

The iPhone 4S is far more technically difficult than the Xiaomi Mi 1!

What's more, in order to avoid some of the shortcomings of the iPhone 4S in his previous life, Sheng Huainan also made some magic changes!

"It is compatible with the dual functions of GSM and CDMA standards at the same time, and supports the latest WCDMA and CDMA two different 3G standards, so as to achieve uninterrupted signal and current global roaming functions in undifferentiated situations, which is too difficult!" Shi Yongxin smiled bitterly.

In the previous life, it meant that the new Unicom of telecom reorganization was not officially established until 08 years, and this era, I don't know if it was the influence of Sheng Huainan, it had been reorganized in advance.

Similarly, the 3G standard is now coming out a year ahead of schedule.

This shows that Sheng Huainan's influence on this era is beginning to get deeper and deeper!

In the later iPhone 4S era, this phone was famous for its poor signal, and of course, the current mate 1 mobile phone has the same poor signal, even worse than the iPhone 4S.

However, the consumers of the Mate 1 mobile phone are basically in the city, especially in the first and second tier cities, although the signal will be poor in the elevator and when going to the staircase corner at night, but the impact is not very large.

In the past, there was no chip design team, and this problem could not be solved, so I had to endure it.

Sheng Huainan looked at the design drawings given by Shi Yongxin, and looked at them carefully for more than 1 hour, and he almost knew what the problem was.

"Let Mr. Zhu come over, it's 9 o'clock now." Sheng Huainan instructed Li Jingshu on the side.

After Zhu Shangzu came over, Sheng Huainan said, "If the Mate 2 mobile phone still uses the original RF chip, there are certain problems, their signal control ability is too poor, and it cannot meet our requirements, Mr. Zhu, the RF chip research and development I told you last time, where has it reached, can you get it out before the Mate 2 goes on the market!" ”

The RF chip in 07 is completely garbage, and the old man is okay, but now it is not possible to do it on the mate 2, and Sheng Huainan does not want to list a semi-finished product when the time comes!

"Mr. Sheng, I sorted out some of the ideas you gave me last time, but in the CMOS/GaAs HBT/pHEMT two sections, although the theory is the same, but they are both design amplifiers, the specific design of different processes is not the same, I am now grasping the team to adjust the frequency of the linear and robust of the chip, but the effect is not very optimistic! The core reason is that the DC, S-parameter, and NF may have certain differences due to the difference in models, not to mention large signal indicators such as P1dB and EVM. Zhu Shangzu stroked his glasses, explained in detail the current research and development (river crab) situation, and shook his head.

Li Jingshu, who was on the side, as Sheng Huainan's assistant, had been keeping her eyes open and trying to absorb what Zhu Shangzu said, although she didn't like the feeling that this kind of knowledge flowed through her brain and there was not a drop left, but in the end, she had to have a sense of frustration, she really couldn't understand what they were saying!

"I think the problem might be with the cloth plate, coupling and how to use it. The higher the frequency, the more severe the coupling phenomenon, and even the coupling between the two backvias may make your chip unstable. Coupling can cause all sorts of problems, and the point is that you often don't have a way to remove or reduce coupling. On the other hand, coupling can cause various problems, but if some coupling can be effectively used in the design, it will improve the design indicators. You should work on this ... Sheng Huainan worked hard to mobilize some knowledge about RF chips in his brain, and he only knew a little about this aspect, so for Zhu Shangzu, a master, it was only a guide at most!

"I probably understand, Mr. Sheng, if this idea is correct, I estimate that I can provide a usable chip in 4 months!" But he didn't want Zhu Shangzu to listen, but the more he listened, the brighter his eyes became, and the shock appeared on his face, and he finally nodded.

What else Sheng Huainan doesn't understand!

He felt like his scalp was tingling!

It's too strong!

No wonder other executives worship Sheng Huainan that day, isn't this a genius among geniuses!

As the first work to be taken out of the Zheku chip, Zhu Shangzu also attaches great importance to it, this RF chip designed now is more advanced than the RF chip provided by Deyi, and it is about 2 years advanced, Zhu Shangzu estimates, this chip can basically provide the best RF chip on the market in 07, it's incredible!

You must know that chip design is monopolized by Western countries or the three countries or regions of the sun, the cold country, and the bend, and there are no relevant design talents in China.

He has done it in a major chip design company before?

No way!

Chip design is a very small circle, and there are only a few powerful Chinese who can keep up with Zhu Shangzu's thinking, and it is impossible for him not to know him!

Shi Yongxin was also a little confused when he listened to it.

"What the hell is this a description of the situation?!"

"Mr. Sheng can talk to Zhu Shangzu in the field of RF chips!"

"This, this, this, omnipotence is not so exaggerated!"

Thinking of this, Shi Yongxin was also completely confused at this time!

Even if he is just asking Zhu Shangzu for needs, as for the Tao in the chip, he can grasp a rough idea, that is, the RF team in the R&D center can communicate one or two, this Sheng Huainan is really terrifying as the main operator.

"Mr. Shi, why are you distracted, I still have three meetings to hold this morning, what problems do you still have not solved now?" Sheng Huainan looked at Shi Yongxin and frowned slightly.

He was crazy busy during this time, and he didn't want to waste even a minute of his time.
