Rebirth: I carry a desktop computer inside me

On September 1, Jiang Cheng paid attention to the price of Bitcoin.

The price per bitcoin is 135 meters.

Jiang Cheng can't remember the specific time of the increase, but he vaguely remembers that it rose at the end of the year.

To this end, Jiang Cheng pays attention to the rise and fall of the price of the currency circle every day.

Many people have large amounts of Bitcoin in their hands, waiting to be sold.

The price of tight goods began to rise.

But after all, it is a virtual currency, and many investors are cautious.

In the next few days, the R&D team was busy with the patent sorting and filing of RF chips.

At the same time, Huaxin Micro was contacted for tape-out, and the 0.35um process was not nano-level, and it did not cost much.

"President Jiang, the fastest batch of tape-outs has been arranged, and it is expected that it will be available before the 10th." Guo Xiaoming reported.

Jiang Cheng nodded, "Okay, first prepare for the announcement, this time we want to lay the foundation for Maple Fire Semiconductor Technology to lead the world." "

As for the complete establishment, it will have to wait for Jiang Cheng to develop a mobile phone SOC chip that is superior to fruit."

"Okay." Although he is technically inferior to Jiang Cheng, he is also from a science class and knows the data in the laboratory of this RF chip.

It is expected to exceed more than 50% of the best RF chips currently on the market.

Guo Xiaoming added, "There are currently rumors that Meizhu is going bankrupt. "

Bankruptcy?" Jiang Cheng frowned, feeling that it was just a rumor, although the previous life Meizhu was a little miserable, he was still alive.

After a few years of struggle, several phones released were still quite popular.

He was miserable by Brother Lianfa.

Speaking of which, this rice and Meizhu are really difficult brothers.

The rice is lambed through the fire dragon pit, and the bamboo is the multi-core pit of Lianfa brother.

"After all, Meizhu is a mobile phone manufacturer that has been operating for several years, and Huang Yang is quite a means, and it is estimated that he will not die for a while." Jiang Cheng thought for a while, "However, you go and contact them and see what their specific situation is."

Guo Xiaoming nodded, "Okay, I'll make a special trip to Zhuhai in the past two days."

He has been following Jiang Cheng for a long time, and naturally understands that Jiang Cheng must have the idea of entering the field of mobile phones when he studies these core chips of mobile phones.

As soon as Guo Xiaoming left, Jiang Cheng used a web crawler to climb the news about Meizhu.

Oh yes!

So many quality problem complaints, all on the list.

Netizen Inva reflected in the forum:

[After mx2 came out, I saw that the phone was so beautiful, it was called an excitement! ] I'm looking forward to buying the order, and then... The tragedy began...

Just after 3 months of use, there was a piece of failure in the lower left corner of the touch screen, and then returned to the factory, it took two weeks before and after, so I had to cheekily ask my colleagues to borrow a mobile phone to use, this cheeky can't hang ah, just bought the mobile phone, there is a problem! ]

There are also many netizens who reported signal problems:

[I was attracted by the appearance and workmanship of MX2, I started the Unicom contract version, there is no signal at home, my wife's mobile phone is also a Unicom card, but there is no problem. ] Heat generation, battery are acceptable, only the signal problem is really going crazy, this is the root of the mobile phone... I have requested a return. ]

The problem of signal, not afraid of short, is afraid of shorter, is afraid of shorter.

Other people's mobile phone signal is full, your mobile phone signal is one grid, or even the same, who can stand it?

In the news of a voice of technology, a so-called insider broke the news that the Meizhu MX2 mobile phone inventory is serious, the mobile phone repair ratio is high, and the cash flow is about to break.

Engaging in mobile phones is afraid of pressing inventory, even if it is to reduce some money, or even lose some money, as long as you can sell the goods, this cash flow can come alive.

But the goods pile up there, and the cost is large.

Some people broke the news that MX2 still has more than 400,000 in stock.

This is after its price cut by 200 yuan.

Even at the price of 2,000 yuan per mobile phone, it is a full 800 million yuan pressed there.

And to engage in mobile phones, which is not using bank money to expand production.

The funds cannot be returned, the interest must be repaid, and all kinds of costs are still being spent, and no one can hold it!

Because of this, Rebs never stocks on a large scale, even if it sells well.

He still likes to let everyone snap up on the official website.

Each batch releases 100,000 or 200,000 goods.

For example, the rice 2S, on the day of its launch, only released 200,000 units, and it was sold out very quickly.

Of course, there are a lot of scalpers in it.

Jiang Cheng thought for a while, but did not make up his mind.

First of all, he does not have much money at his disposal now, even if the fast charging technology does make some money, but the profit is only about 40%.

Therefore, it is only a profit of more than 100 million.

The copyright money and profit dividends of Maple Fire Games' foreign operating companies have also arrived, and with the income of China, it is only more than 100 million yuan.

That's too little money for a medium-sized mobile phone maker.

Moreover, Huang Yang is a little paranoid and too controlling, and Jiang Cheng has a strong guard against him.

A few days later, Guo Xiaoming returned the words.

Meizhu's life is very difficult, but the bank payment can still be supported until next year, and it can't be poured for the time being.

Company executives are willing to have financing.

However, Huang Yang's attitude is not clear at present.

"Okay, let's contact first for the time being, let's not be in a hurry." Jiang Cheng hung up the phone.

If he wanted to spend billions of dollars, Jiang Cheng felt that it was not worth it.

If you have money, it's better to have your entire brand and directly enter the mobile phone market!

It's just that Jiang Cheng still has some good impressions of the brand Meizhu and does it very exquisitely.

If you have the opportunity and don't spend much money, it's good to buy.

---- ( ̄) ̄) ↗ On September 9---, Jiang Cheng got the

RF chip module that was successfully tape-out.

The entire RF chip is stored on an experimental mobile phone motherboard, occupying 1/3 of the motherboard space.

It has integrated power amplifier (PA), filter (Filter), radio frequency switch (Switch), low noise amplifier (LNA) and other components.

And this whole set is developed and designed by Jiang Cheng led the team, except for a few patents that cannot be bypassed, all of them are self-developed patents!

In the laboratory, there are a number of mobile phones disassembled motherboards.

Now, engineers are replacing the RF circuit motherboard.

Prepare for mobile phone RF signal experiments.

"Experimental Group No. 1, signal strength -40dBm, excellent; Control group, signal strength - 66dBm. "

Experimental group two, signal strength -64dbm, excellent. Control group, signal strength - 103dBm. "

......

In different signal environments, through tape-out sample tests, the R&D team collected and sorted out data.

But obviously, the data quality is very good.

The experimenters will also replace the MX2 mobile phone with a new RF chip, which is at least 60% higher in terms of signal strength and call quality compared with the original.

The more you experiment, the more incredible it becomes.

This extremely excellent RF device was really developed and manufactured from my own hands.

You know, in today's China, there are only one or two manufacturers that produce RF chips and RF communication modules, that is, Kyoto Guangjia Electronics.

Moreover, there is a significant gap in the level of technology compared with foreign countries.

But today, Jiang Cheng can proudly announce that Maple Fire Semiconductor will be the leader of domestic RF chips.

"Mr. Jiang, the sample test was very successful!" Chen Xiao held the thick data record book and reported to Jiang Cheng with an unstoppable smile.

So, what's next?
