Texas Instruments LMX2594 Frequency Synthesizer

09.08.2017

Texas Instruments has released a new LMX2594 frequency synthesizer with a wide operating frequency range and unprecedented high microwave signal parameters. LMX2594 has best in class phase noise: -236dBc/Hz; jitter 50 fs and high operating frequency - up to 15 GHz without the use of an internal multiplier.

The synthesizer contains a synchronization input, allows you to implement frequency jumps (frequency ramping), and the output signal can be taken on two differential outputs.

The LMX2594 allows you to synchronize the outputs of multiple chips, as well as provide a predictable, stable delay between input and output. A fast calibration mechanism allows you to change the frequency in 20 µs. The output power adjustment range is from 7 to 15 dBm.

The synthesizer is powered from a single voltage of 3,3 V; Built-in LDOs eliminate the need for additional on-board regulators.

Applications for LMX2594:

Measuring equipment.
High speed data converters (JESD204B).
Cellular 5G networks.
Communication infrastructures of the millimeter range.
Phased array antennas and beamforming.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

sea turtle chemical cocktail 01.07.2017

Australian researchers from the University of Queensland found in the blood of green turtles living on the Great Barrier Reef, a real "cocktail" of drugs and household chemicals.

The biologists examined the turtles, which showed signs of inflammation and liver dysfunction. It turned out that in the bloodstream of animals there are impurities of drugs for heart disease and hyperuricemia, as well as cosmetic and industrial chemicals.

The researchers studied the condition of the turtles living along the coast of Queensland, as well as the inhabitants of the outlying islands north of the reef. The study was carried out within the framework of the World Wildlife Fund (WWF) Australia.

According to Amy Heffernan from the University of Queensland, people constantly "leave" a chemical trail behind them, but it is still unclear what effect it has on the environment.

WWF Australia experts suggest that the obtained data on the state of turtles can become a tool for biological monitoring. With it, they want to find out what chemicals get into the waters and how they affect marine life.

In 2015, researchers found that the chemical oxybenzone used in sunscreen is causing massive damage to coral reefs around the world. According to the study, it causes deformation of young corals.
