What is an active antenna and passive antenna?

Thanks to the dynamic development of television broadcasting in the modern world, there is probably no person who does not encounter antennas. In order to watch their favorite TV shows in the best quality, the user needs to connect the antenna to his receiving equipment. And then the question arises: which antenna to choose, active or passive? In this article, we will consider in detail the features of each antenna, as well as the scope of their application. But first of all, it is necessary to give a detailed definition of the very term “antenna” and briefly describe the history of creation.

Heinrich HerzAntenna is a special device whose main task is to receive or emit radio waves. It converts the fluctuations of the electric current into a radio wave or vice versa. As can be seen from the definition, antennas can operate on reception, transmission, or transmission. The simplest antenna operation Continue reading

What is LNB?

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

What is a BUC?

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.
