The acronym LNB stands for Low Noise Block. This device is installed in front of a satellite dish, which receives a very low signal and amplifies it, changes the signal to lower frequencies and transmits them via cable to the receiver.
The expression Low Noise refers to the quality of the first transistor preamp. Quality varies in units designated as “noise temperature” or “noise figure”. The lower the noise temperature, the better. So, LNB with a noise temperature of 100 K is twice as good as – 200K. C-band LNBs typically have the lowest noise temperature, and Ka-band LNBs have the Continue reading
The basic architecture of a conventional satellite terminal is based on the historical desire to make the most open and free construction. Over the years, this concept has developed global competition in creating the functionality of hardware units, and as a result, the architecture has improved and costs for the end user have decreased.
However, since operational requirements have changed and technology has improved, it is also necessary to change the system architecture in order to achieve additional benefits. The CPI amplifier with an integrated L-band frequency converter (BUC) allows you to reduce costs and increase the reliability of data transmission at low and medium frequencies by eliminating duplicate functions in a conventional RF terminal circuit.

Video Electronics Standardization Association (VESA) announced the release of DisplayPort 2.0 audio / video standard.
DisplayPort 2.0 (DP 2.0) is the first global update to the standard since March 2016. It provides for a three-fold increase in channel bandwidth, which provides support for resolutions over 8K, a higher screen refresh rate and high dynamic resolution (HDR) for high resolution, improved support for various display configurations, and an improved user interface for working with augmented / augmented reality (AR / VR), including support for virtual reality systems with a resolution of 4K and higher.
