Going back to the single-structure CMSO process RF chip, although this thing cannot directly meet the power required for wireless communication, it is not completely useless.

In fact, when the project team was first established, Meng Huaiying led the team to try on this road, and the final product was pitiful in terms of power, but fortunately, Wang Zhengguo understood the situation in time and proposed to use this ultra-low power ultra-low cost CMOS radio frequency technology to develop a radio frequency card attendance system.

Therefore, in 90 years, Kaiyang Semiconductor used the tall RF card attendance system, which was really awesome.

After that, the system was quickly introduced and used by Yaoguang Electronics, so as to effectively improve the efficiency of factory attendance, due to the ability to eliminate the very "humanized" manual attendance system, this system is also beginning to be rolled out in large domestic factories at a visible speed.

....

Meng Huaiying at the summit only mentioned that she had invented a CMOS hybrid structure, but the specific structure was, of course, strictly confidential, and only the maximum test power data was announced.

It is indeed remarkable that CMOS technology can be further developed to make it have quite good RF power, which is already the best semiconductor RF material except for gallium arsenide.

"The emergence of new technology, we can develop enough cheap wireless communication equipment, at present, our wireless communication network in Chengdu has begun to build, although it is not yet possible to achieve wireless voice communication, but enough to achieve two-way communication of text signals, both to receive text messages, but also to send text messages. ”

At this time, most of the pagers on the market can only receive messages passively, which is similar to the semi-active radar seeker, which can only receive signals, and the user can know that others are looking for you, but they cannot send messages back through the pager.

Although there is also a paging that can communicate in both directions on the market, the price is ridiculously high, and this time Kaiyang Semiconductor wants to do it, which is to make the high-end products in the pager: two-way pagers fully domestic and cabbage!

This is not difficult to achieve, and the simplest solution is to install miniaturized T/R components inside the machine.

It doesn't take too much, only one T/R component per machine is enough, and civilian equipment does not need to consider the special needs of military equipment, and then wait until the production goes up, and the price can continue to fall.

Who said that the T/R component can only be used for military purposes, as long as you want, the change of military technology to civilian is just a thought.

As early as 1990, Inspur has cooperated with Motorola to produce a pager that can realize the function of Chinese character display, and has been put into operation in 1991, but this cannot stop the footsteps of Kaiyang Semiconductor.

According to Kaiyang Semiconductor's previous plan, Meng Huaiying's team has launched the answering pager that is being trial-run in Shudu, that is, the kind of product that can send the internal preset information of the machine immediately after receiving the information to notify the sender that the information has arrived.

This kind of pager is not the first time to eat crabs in the market, but fortunately, all its core components can be completely made in Kaiyang, and the ultra-low price also makes it highly competitive in the market.

Kaiyang Semiconductor did not personally produce terminal paging equipment, but packaged and sold core components by set, and downstream companies produced terminal equipment.

The entrepreneurs of Rongcheng High-tech Industrial Park are all smart people, these guys only need to buy core components from Kaiyang, and then design some external power supplies, displays, and input parts by themselves, and then they can go on the market.

To put it bluntly, the role played by Kaiyang Semiconductor now is that of giants such as Qualcomm and MediaTek, and I produce the most core, the most difficult, and the most profitable part, and after that, other aspects are completely handed over to downstream manufacturers to integrate and sell.

Among the six downstream pager factories, Wang Zhengguo was most surprised that he actually saw a super bull, in the list of information, there was a "BBK Electronic Equipment Co., Ltd.", and its legal representative was Duan Yongping.

Well, Wang Zhengguo admits that he was taken aback at the time.

The big bull didn't go to Zhongshan City to engage in the Xiaobawang game machine, but came to the Rongcheng High-tech Industrial Park to start a business, which is really embarrassing, and the current Rongcheng High-tech Industrial Park has indeed changed too much.

It was only after chatting and communicating that I found out that it was because Tang Jun had successfully started a business in Chengdu before and earned a net worth of tens of millions with his bare hands, followed by hype and reports by various news media, which gave many high-tech talents who wanted to go to sea the courage.

This is the case for Duan Yongping, who himself is engaged in the wireless electronics industry, and after two years of work, he studied econometrics at the Department of Economics of Renmin University for a second time and obtained a master's degree.

With technology and management, this old Duan came to Rongcheng after graduation, and did not engage in card game machines like the upper plane, but directly recognized the pager equipment business, and this led to the early debut of "backgammon".

Well, backgammon pager, it sounds like it fits well with the aesthetics of the broad masses of the people of the nineties.

.....

The answering pager that has been put into the market can only be regarded as the lowest-end product, and in Meng Huaiying's team plan, the pager that realizes two-way communication of text messages is the main event, which can almost be regarded as having all the functions of mobile phone text messages.

However, this also brings some problems, first of all, the need for a larger LCD screen, and secondly, the need for a keyboard that can input Chinese characters, in the early nineties, the Chinese character input of the nine keyboards is not yet fully mature, so Kaiyang Semiconductor's input method business department is seizing the time to do key problems.

As the function of the two-way pager gradually becomes stronger, a special central processing unit is needed, but fortunately, there is no problem for Kaiyang Semiconductor in this thing, so you can do it casually.

In order to show its identity, the two-way pager positioned in the high-end market is directly integrated into the pager by using the existing antenna system and speaker of the pager itself, and then adding an integrated circuit radio module and an audio decoding module.

Someone even said frankly that Kaiyang Semiconductor should go to Germany to get the MP3 audio format license as soon as possible, so as to prepare for the next step of integrating digital music playback capabilities into mobile phones.

As for whether to get the MP3 player out alone, this is of course a must, but this kind of terminal-oriented consumer electronic products, when the time comes, more may have to be handed over to Yaoguang Electronics to do, Kaiyang Semiconductor is now determined to be the predator behind the predator, and it will not be easy to directly produce terminal equipment on the market.
