Piezoelectric filters on SAW. Reference data. Piezoelectric filters on SAW

The operation of surfactant filters is based on the phenomenon of selective reception and transmission of acoustic waves traveling along the surface and piezoelectric substrate. Compared to LC filters, they have a flatter peak of the frequency response, greater slopes of the frequency response at the edge of the passband, stability and accuracy. Surfactant filters are used instead of concentrated selection filters.

Wideband and midband filters are used for channel or group selection of signals and frequency-selective elements, rearranged in frequency and band.

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 ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Bluetooth 5 specification approved 08.12.2016

The Bluetooth Special Interest Group (SIG) has officially adopted the Bluetooth 5 specification, which provides further improvements to the wireless communication of the same name.

The key innovations of the approved standard compared to Bluetooth 4.2 are called a twofold increase in speed and a fourfold increase in range in Low Energy (LE) mode.

Standard mode will maintain compatibility with previous Bluetooth specifications. But at the same time, the energy efficiency of the modules will increase. In addition, the number of simultaneous connections to one module has been increased by eight times.

The Bluetooth 5 specification also includes a number of changes to reduce potential interference with other wireless communications systems.

The Bluetooth 5 standard is well suited for use in the IoT segment. By 2021, ABI Research estimates that there will be about 48 billion devices worldwide with the ability to share data over the Internet. Of these, almost a third will support Bluetooth wireless technology.
