BALF-NRG-01D3 - balun for wireless BLE devices

30.09.2016

A typical RF transceiver output connection scheme provides for a passive high-frequency matching chain with an antenna of several discrete components. This complicates the product layout, increases the dimensions of the printed circuit board, increases the cost of installation and logistics of components.

When designing Bluetooth Low Energy RF devices based on STMicroelectronics components, you can use the BALF-NRG-01D3 miniature integral balun, which replaces up to 10 discrete LC components.

Balun BALF-NRG-01D3 is designed to work with BLUENRGQTR, BLUENRG-MSCSP, BLUENRG-MSQTR and BLUENRG-132 chips. When using it, the circuit of the high-frequency part of the product is greatly simplified, while the area of the printed circuit board is also reduced.

The BALF-NRG-01D3 balun is manufactured using a unique technology by depositing miniature capacitors and inductances on a glass substrate. Operating frequency range 2400 - 2500 MHz, chip size 1,4 x 0,85 mm.

Features of BALF-NRG-01D3:

Zant unbalanced output = 50 ohms
Input impedance matches the BLUENRG family of chips
Low insertion loss -1,1 dB
Low amplitude (0,5 dB) and phase (7°) unbalance
Hull height < 670 nano m
High RF parameters

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

AUO to release 4,3-inch AMOLED panels 05.08.2012

AU Optronics (AUO) President Paul Peng has announced plans for mass production of 4,3-inch AMOLED panels. According to him, the production of products was supposed to begin in the second quarter of this year, however, due to some delays, it had to be postponed until the third quarter.

According to Mr. Penh, the development of new technologies and the development process are not the only challenges faced in the production of panels. An important factor is close cooperation with suppliers of materials and players in the final market.

The products in question will have a density of up to 257 ppi (with a diagonal of 4,3 inches, this corresponds to a resolution of 960 x 540 pixels), which is a record for AMOLED panels to date. AUO engineers are working to integrate in-cell touch technology into AMOLED panels to make displays thinner and lighter, as well as achieve higher sensitivity.

Another direction of development is the one glass solution (OGS) technology, the essence of which is to combine the elements of the display and the outer glass together, which also makes it possible to reduce the thickness of devices. In addition to smartphones, the technology will find application in ultrabooks and tablets, but their share will be only 2-3%.
