In recent years, due to the application of 5G, everyone's attention to RF GaN has increased. Qorvo also believes that GaN is very suitable for providing the high frequency and wide bandwidth required by the millimeter wave field. It can meet the performance and small size requirements, as shown in the figure below. Applications that use the millimeter wave frequency band require highly directional beamforming technology (beamforming focuses the radio signal into a strong directional beam, thereby increasing power and minimizing interference on user equipment). This means that the RF subsystem will require a large number of active components to drive a relatively compact aperture. GaN is very suitable for these applications, because it provides strong performance in a small package size is one of its most notable features. According to a report by Yole, an internationally renowned analysis organization, in early June, the GaN radio frequency industry started with silicon carbide-bas...

Today, RFID technology has entered all walks of life, exerting powerful digital collection capabilities in different application scenarios and links. However, in practical applications, label identification often encounters various challenges, including not only environmental factors, but also product technology and so on. For manufacturers who use RFID systems, easy-to-use RFID tags are a key to the success of the project. Objectively speaking, an easy-to-use RFID tag contains many elements, such as excellent performance, strong storage capacity and environmental adaptability, as well as an aesthetically pleasing antenna design, an irresistible price, etc. From the perspective of RFID label manufacturing, the processing methods of each link including chip, antenna design, binding, compounding, and packaging will have an impact on the final finished label. In this process, not only must the performance of the RFID tag be guaranteed, but also the consistency of the tag must be ensured. ...

With the continuous improvement of social productivity, the scale of the logistics industry continues to grow. In this process, more and more new technologies have been introduced into the major logistics applications. Due to the outstanding advantages of RFID in wireless identification, the logistics industry began to adopt this technology very early. However, in practical applications, the industry's acceptance of RFID technology will still proceed from its own actual conditions. For example, in the e-commerce market, in response to the impact of counterfeit goods, RFID technology is often used in high-value products such as wine and jewelry, with the main purpose of anti-counterfeiting and traceability. For example, JD Wines combines blockchain and RFID technology to solve the problem of high-end wine in anti-counterfeiting. However, the value realized by RFID is diversified. The application of RFID in the logistics field runs through the entire process, including the collectio...

Why is RFID technology superior to barcodes? RFID technology and bar code are two different technologies, have different applicable scopes, and sometimes overlap. The biggest difference between the two is that barcodes are 'visual technology'. The scanner works under the guidance of people and can only receive barcodes within its field of view. In contrast, radio frequency identification does not require seeing the target. The radio frequency tag can be read as long as it is within the range of the receiver. The barcode itself also has other shortcomings. If the label is scratched, contaminated or peeled off, the scanner will not be able to identify the target. The barcode can only identify the producer and the product, but cannot identify the specific product. The barcodes affixed to all the same product packaging are the same, and it is impossible to identify which products expire first. What is the difference between RFID technology and barcode? Conceptually, the two are ver...

Although the business society already has a stable and complex structure, the changes in the market always make people wonder. Since 2020, a new crown epidemic has caused a huge impact on the global economy, and almost all industries have been severely affected. The first thing the epidemic comes is is a crisis, but the crisis often gives birth to new opportunities for development. For the RFID industry, the emergence of the epidemic on the non-contact economy is an opportunity, gestating new growth points. Under the influence of the epidemic, many industries have become more aware of the benefits of RFID. For medicine, the use of RFID technology can realize the traceability management of medicine and medical equipment, and the realization of these functions is based on non-contact. Therefore, in the post-epidemic era, the value of using RFID technology to improve the medical management system has been seen by more and more hospitals and medical organizations. The impact of the epidemi...

The second important aspect of RFID classification is whether it is necessary to read multiple tags at the same time. In order to realize this function, the technology adopted in communication is (anti-collision) 'anti-collision'. Reading multiple tags at the same time is often talked about as RFID is far superior to graphic codes, but if there is no anti-collision function, the RFID system can only read and write one tag. In this case, if more than two tags are in the readable range at the same time, it will cause a reading error. Secondly, let's briefly explain the working principle of the anti-collision (anti-collision) function. Even the RFID system with anti-collision (anti-collision) function does not actually read the contents of all tags at the same time. When multiple tags are detected at the same time, the function of searching for signals and preventing collisions starts to operate. In order to search, first determine the search conditions. 1). First, the reader...

Previously, MORLAB has completed the testing and certification of several RFID products. Let's take a look at the RF test points of the next UHF band RFID. At present, the UHF RFID operating frequency band used in Europe is between 865MHz and 868MHz, and the power does not exceed 2W. According to the R&TTE directive, the radio frequency test in the CE certification needs to refer to the harmonized standard EN302 208-2 for testing. Usually, a complete RFID system has two parts: RFID reader (Interrogators) and RFID electronic tags (Tags), and the tests of the two are also different. The following is an introduction to the test of a scanner. The modulation method of this product is ASK, the power is 30±3dBm, and the effective working frequency points are: 865.7MHz, 866.3MHz, 866.9MHz, 867.5MHz. The spectrum diagram under the working condition of the product After a comprehensive evaluation of the customer's product by MORLAB engineers, the product is classified as a handheld ...

Speaking of RFID , in fact, it is widely used, and it is even used every day, such as our second-generation ID card. Mr. Xuetang said that the application of RFID in daily life is good~+RFID (Radio+Frequency+Identification, radio frequency identification) is a wireless communication technology that can automatically identify target objects and obtain related data through radio frequency signals. It is the Internet of Things One of the commonly used short-range wireless communication technologies. +RFID electronic tags have a complete set of modulators, encoders, memories, controllers and antennas, according to application requirements, you can choose the built-in battery to work together. +Compared with ordinary bar codes, RFID technology has the advantages of waterproof, anti-magnetic, high temperature resistance, long service life, long reading distance, encryption of label data, and larger storage capacity that ordinary bar codes do not have. +The electronic tag can realize the read...

The radio signal recognizes a specific target and reads and writes related data, without the need to establish mechanical or optical contact between the recognition system and the specific target. The radio signal is an electromagnetic field tuned to a radio frequency to transmit data from the tag attached to the item to automatically identify and track the item. Some tags can obtain energy from the electromagnetic field emitted by the recognizer during identification, and do not require a battery; some tags have their own power source and can actively emit radio waves (electromagnetic fields adjusted to radio frequencies). The label contains information stored electronically and can be identified within a few meters. Unlike the barcode, the radio frequency tag does not need to be in the line of sight of the recognizer, and can also be embedded in the tracked object. Expansion information: Many industries have used radio frequency identification technology. By attaching the label to a ...
