When it comes to Qorvo, many people may not understand, but if TriQuint and RFMD, people in the electronics industry should have more or less contact, Qorvo is the merger of the two companies. What kind of product services will RF and front-end market bring to the merger of RF duo?
At the 5th “Trend, Innovation, and Win-Win†China ICT Media Forum and 2016 Industry and Technology Outlook Seminar held by Yiwei News, Qorvo, the Asia-Pacific manager of Qorvo Mobile Products Market Strategy Department, brought about Qorvo. A wonderful speech on the status quo and product development.

Opportunities and challenges brought by fast-growing networks
“Qorvo currently has two main business directions, namely mobile and infrastructure, offering a wide range of products including PA (power amplifier), filter (filter), switch/antenna (switch/antenna), etc. Manager introduction.
Tao Zhen, Asia Pacific Manager, Qorvo Mobile Product Marketing Strategy
In the past few years, the global intelligent mobile devices have experienced explosive growth, data demand has increased, and operators' networks have evolved from 3G to 4G and even 5G. The huge market demand has brought huge business opportunities to RF front-end vendors such as Qorvo. According to Tao Manager, in 2014 alone, Qorvo's sales were close to $3 billion, and its total number of employees employed worldwide was close to 7,000.
But with the development of networks and devices, it has also brought great challenges to front-end vendors.
We know that for smart phones, baseband and radio are the key to "communication" with the outside world, and radios are composed of front-end modules (PA, switch, filter). A single PA chip can only process signals in a fixed frequency band. This has not been a problem in the past 2G era, but with the popularity of 4G, everything is changing.
Modulation and demodulation technology is more and more complicated
The data access traffic is increased, the modulation and demodulation methods brought by different communication technologies are more difficult; the frequency band of mobile communication is increased; the complex network environment; under the influence of various conditions, the design of the RF front-end solution is more and more complicated, PA, switch The number of filters is also increasing, the loss and isolation problems are increasing, and the frequency of interference is increasing, which brings higher demand for RF front-end development.
Increase in RF complexity
Tao Manager also said that because of the shape, PCB size and interference suppression requirements of mobile devices, the integrated integrated solution for RF front-end is also advancing. This is another challenge for Qorvo RF front-end manufacturers.
Increasing demand for highly integrated RF front-end solutions
In addition, network operators have introduced the concept of carrier aggregation in order to make full use of the spectrum and improve network quality and data throughput. That is to say, multiple carriers are aggregated into a wider spectrum, and some discontinuous spectrum fragments can also be aggregated together, which can well meet the spectrum compatibility requirements of LTE and LTE-Advanced systems, and can not only accelerate standardization. Processes also maximize the use of existing LTE equipment and spectrum resources.
Undoubtedly, in the multi-spectral and multi-standard environment, the RF front-end has ushered in an unprecedented challenge.
Qorvo's RF Fusion caters to market needs
As mentioned above, carrier aggregation is the key to improving the network experience. According to Tao Manager, there are three types of carrier aggregation: the first is inter-band aggregation, which refers to the aggregation of spectrums in different frequency bands; the other two types are unified bands. In-band adjacent polymerization and in-band non-adjacent polymerization within. How to solve various intermodulation interferences generated between different uplink and downlink carrier frequencies has become a concern.
"At the same time, because the type of aggregation pursued by operators differs due to the ownership of the spectrum, the geographical distribution, and the amount of bandwidth to be aggregated, for RF front-end vendors such as Qorvo, more consideration is needed on multiplexing, switching, and switching. , antenna architecture, size, performance and compensation, etc.," Tao Manager stressed.
Carrier aggregation mode
With the advent of carrier aggregation and multi-mode multi-frequency, the advancement of RF front-end technology challenges will undoubtedly increase costs. At the same time, the complex spectrum and network environment have given the RF architecture a variety of options. Manager Tao stressed.
Current RF architecture options
Qorvo is also doing in-depth research in these areas, especially in RF integrated solutions, Tao Manager believes that this is undoubtedly a major challenge in the RF field.
As a globally renowned RF supplier, Qorvo offers RF Fusion solutions that offer different RF solutions for different product design needs.
Tao said that the solution combines the industry's best power amplifier efficiency, filtering and duplexing, and cellular switching to deliver industry-leading performance. Together with the RF Fusion family of products, the integration options now offer a single configuration and a new solution that includes all major RF transceiver functions across the entire high, medium and low frequency range. Basically can cover the needs of different users.
RF Fusion Series Solutions
Qorvo's attack on the RF field benefits from its product coverage and production assurance.
“Qorvo's products are designed, manufactured, tested and packaged by their own factories, so that the quality control of the products can be done better in the process.†Tao Manager pointed out.
In addition, at the beginning of the article, we have already mentioned that Qorvo involves all the production of the RF front-end industry chain, and more importantly, Qorvo can develop different products for different market needs.
For example, in the field of PA, Qorvo will use CMOS PA on cost-critical low-end products, and its GaAs PA will be used in products with high demand for high gain/low power consumption.
The same is true for filters. SAW, BAW, TC-SAW, Qorvo have different solutions for different environments and different costs.
When talking about the future, Tao Manager pointed out that 5G is necessarily a development trend. For RF front-end manufacturers, it is more important to pay attention to spectrum and modulation and demodulation methods, and to take into account the different needs of 5G technology caused by the outbreak of IoT. .
When asked about the form of the RF front-end under 5G, Tao Manager pointed out that integration is undoubtedly the future development direction.
