Nova 5z listed in October 2019 took the lead in achieving the domestic system of the RF chip of 4G mobile phones, got rid of the binding of US companies.
Previously, in Huawei mobile phone, Haisi chip has taken a relatively dominant position.

According to this information, let's explore how the Haisi chip is coming today.
Haisi Semiconductor Co., Ltd. was established in 2004. The predecessor is Huawei Integrated Circuit Design Center. In 2009, the first application processor K3V1 was launched.
Huawei mobile phone, the first Haisi chip, the first March 2013, is listed in March 2013, and the 40nm process does not have a K3V2 quad-core processor that does not have an integrated baseband, and supports a power management chip.
Be
The Kirin 910 processor released in the same year is a quad-core processor using a 28nm process, and the first integrated baseband Balong 710. Since then, the processor of Huawei mobile phone is basically produced by its own, Kirin processor.
Of course, more than this, Haisi then sets the target in the audio decoder chip and radio frequency transceiver chip.
2 Haishi frequency transition chips and 1 audio decoding chip have occurred in Huawei 6 in June 2014.
The Kirin920 processor includes a 28nm process, as well as two power management kits. Glory 6 has used 6 Haisi chips.
Be
In 2015, as the most flagship of Huawei annual, almost all the flagship configurations were included in the fuselage. The processor is the latest Haisi Kirin 950 at that time, and the baseband is still Balong 720.
More than the previous generation of Kirin 930, each parameter has improved.
Be
Haisi Hi6523 battery management chip appears in Haini Mate9 in 2016. Includes the Kirin 960 processor, the number of MATE9 Haisi chips is increased to 8.
Be
In 2017, Hai Si began to get involved in the WiFi / BT / GPS chip and a radio frequency portion other than RF transceiver.
In October 17, the glory 7X was found on the Glory 7x, I found Haisian's WiFi / BT / GPS chip.
Be
This Hi1102 is not used by Mate 10 Pro, 1 month, 1 month late, although this Hi1102 is not used. But the processor upgrades to the Kirin970 of the 10nm process, the baseband is also updated to Balong 750.
Plus the new two Hai Si low noise chips, the Haisi chip in the Mate 10 Pro increased to 9.
Be
In 2019, Haisi finally completed the "dedication" while achieving the localization of the 4G mobile phone RF chip.
There were 11 Haisi chips in NOVA 5z released in 2019, with radio frequency parts, including 1 RF transceiver chip, 3 power amplifiers, and 2 low noise chips.
The most important thing is that in the whole machine, there is no chip from the United States. (The specific disassembly content of NOVA 5Z will be served in the first time.)
Be
As a 5G year, Huawei also released the Mate 30 Pro 5G flagship mobile phone.
Although the radio frequency part of this mobile phone still uses Village and Qualcomm radio frequency chips. However, the processor, power, audio, and partial RF chips are still using the Haisi chip. A total of 21 totaled.
Be
And Huawei used the first integrated 5G baseband processor - 990 5g in Mate 30 Pro 5G. Pack the plug-in Balong 5000 directly into the processor.
Not only that, but compared to Kirin 990, Kirin 990 5G has made some adjustments in many places.
Be
Be
At present, Haisi has been able to get localization from the processor to the RF chip from the processor to the RF chip.
It is believed that the RF chip of the 5G mobile phone should come at a faster speed.
Huawei will develop the chip from the processor that starts, step by step to today's RF chip. Which changes have been the emergence and development of the latch? So, next time, let's analyze the development of these sets. (: 玥)
