General Information

The PERTE Chip program is improving industrial capabilities in Europe’s battle for technological sovereignty

The importance of technological sovereignty for Europe became clear during the COVID-19 pandemic, when significant supply chain problems made it difficult to obtain microelectronic components from Asia. The PERTE Chip project is one of the Spanish government’s Strategic Projects for Economic Recovery and Transformation (PERTEs) and is aimed at driving development of the semiconductor industry in Spain. It is now benefiting from an investment of €12 billion for the 2021-2023 period, and it includes participation by Spanish and foreign companies in collaboration with universities and research institutes.

One of the goals of the PERTE Chip program is to expand research and development efforts related to semiconductors by creating an innovation and startup ecosystem in this area, training specialized talent, and attracting foreign investment. There are also plans for building a semiconductor production facility in Spain, and although this is no easy task, it will allow companies to produce next-generation chips and electronic components there.

In relation to this subject, two companies from the Televes Corporation have spent years establishing their leading-edge positions. Since 2010, we have been working on the designs and backend processes required for developing semiconductor circuits, and in 2020, we created Maxwell Applied Tech, a company specialized in designing customized microchips for radio frequency applications, using gallium arsenide and gallium nitride as a substitute for the traditional silicon. In addition, at its facilities and Santiago de Compostela, Spain, Televes has already developed the assembly process for those monolithic microwave integrated circuit (MMIC) components.

Jaime Martorell, a special delegate for the Microelectronics and Semiconductors PERTE, recently made a visit to the Televes Corporation to learn more about its lines of activity involving microelectronics and semiconductors. He gave a positive assessment of the activities we have established there for designing and assembling semiconductors, including our customized solutions that can offer significant competitive advantages. The plan developed by Televes will ensure that our facilities, machinery, and manufacturing processes remain up-to-date and can always comply with the market's existing demands, while also allowing us to develop new technological and industrial capabilities.

Participation in the PERTE Chip program will also make it possible for Maxwell Applied Tech and Televes to attract and retain the industry’s best talent, while contributing to the country’s overall development and enhancement plan. When designing solutions and assembly processes, additional challenges are presented by the race for miniaturization and the need for integration and use of increasingly high-frequency bands. Televes Corporation is ready to take on these challenges and contribute to advancement of the semiconductor industry in Spain and Europe.

Defending the radio spectrum: the importance for broadcasting

The organization known as the Wider Spectrum Group has submitted a request to the European Commission, the European Council, and European Conference of Postal and Telecommunications Administrations (CEPT), asking them to maintain the current assignment of the UHF band by supporting "No Change" at WRC-23. The current assignment of frequencies is essential for European content creation and distribution through radio broadcasting and PMSE, and making changes would cause immediate harm as well as long-term implications for investment and innovation in the industry, a negative impact on universal access to terrestrial TV and broadcasting of live events such as concerts, and obvious implications for the associated jobs.

While acknowledging the value of the opinion expressed by the Radio Spectrum Policy Group (RSPG), in order to reach a compromise with the minority countries from Region 1 that are insisting upon a regulatory change, the Wider Spectrum Group is asking the European Commission to submit a proposal to the Council opposing co-primary assignment and supporting "No Change" for UHF band assignment at WRC-23.

The organization has also requested neutral wording for agenda items at WRC-31 that affect the European 470-694 MHz cultural band, with that wording modified to include the possibility of reviewing the spectrum’s use and service needs existing for the 470-960 MHz frequency band in Region 1, and the possibility for regulatory actions regarding the 470-694 MHz frequency band based on that review.

The Wider Spectrum Group is therefore repeating its efforts to obtain a firm position from the EU against co-primary assignment to mobile services, and in favor of "No Change" in assignment of the UHF band at WRC-23. This is based on the critical importance of that assignment for European content and for freedom of expression and pluralism through regulated communication media.

How to balance TV signals from two antennas directly on the mast

When signals are received from two antennas, there are many devices that can be installed on the mast to combine or amplify those signals. However, only our SmartKom amplifier can perform effective balancing too. By using its automatic adjustment button, the SmartKom achieves perfect balancing thanks to individual processing of each channel.

This type of balancing is not possible when using a mast amplifier with various inputs, because its broadband operation does not allow it to compensate for level differences in the channels being received by the antennas.

The SmartKom amplifier also has another advantage: Although its automatic search button can be used to find the channels, the user can also fine-tune that automatic search by removing other (usually spurious) channels received at the antenna pointing directions, which may reach the level threshold but often without achieving the quality threshold. The SmartKom app can therefore be used to differentiate desired and undesired channels for distribution.

One good example of this scenario is in the region of Galicia, Spain, near the border with Portugal, in locations where channels are received from Domaio (in Moaña, Galicia) as well as from Monte do Faro (in Valença do Minho, Portugal).

FAQs

Should you install Class I or Class II light fixtures?

These classifications are based on the systems used to protect against electrical shocks. Depending on the class, different measures are used to prevent exposure to hazardous voltage levels in parts accessible to users. Class I light fixtures use basic insulation between the accessible parts and the conductor elements, and they must also have a protective grounding connection to reduce the risk of electric shock. In contrast, Class II light fixtures include not only basic insulation to protect against electric shocks, they also have double insulation between the accessible parts and conductor elements. This allows these product to ensure safety without depending upon a protective grounding connection or the installation conditions. There tends to be a certain amount of controversy about whether to use Class I or Class II light fixtures. Class II light fixtures are safer than Class I, because their safety does not depend upon their installation location. This is of major importance for older installations, or those where the grounding connections, cables, etc. will not be completely renovated. It must be remembered, however, that if the grounding systems are in good condition and comply with the levels required by the regulations, Class I equipment has an excellent level of protection, not just in terms of electrical safety, but also by offering increased protection against overvoltages in the electrical line while helping to dissipate voltage spikes. In summary, Class II light fixtures can be recommended for installations that have not been entirely renovated, with Class I only recommended for entirely renovated installations.

How to use the ASuite app to configure the SmartKom amplifier

Manual selection of filtering, output level, and equalization

Manual selection of filtering, output level, and equalization

With automatic configuration, pressing just one button will enable the SmartKom to detect the channels and assign the filters and output levels to them. It also manages the antenna’s powering if necessary to increase the output level to the maximum possible. Although these are very practical and useful automatic features, professionals with advanced know-how usually prefer to perform configuration using the ASuite app, which lets them manually select the filters, channels, and output levels, optimizing the output signal.

This manual configuration requires the ASuite app to be installed on an Android or iOS mobile device with Bluetooth.

The app is started up on that device and then connected to the SmartKom amplifier by pressing the “Connect” button. Next, clicking on the “Import” option, represented by a down arrow icon, recovers the self-configuration settings saved on the SmartKom device. The user can then manually edit the configuration parameters:

How to use the ASuite app to configure the SmartKom amplifier

Selecting the filters

There may be cases where one or more undesired channels from another repeater were added during the initial automatic configuration, or it may be possible to receive certain channels with better quality through another UHF input using another antenna, or the user may simply want to add or remove distribution of a specific channel.

All of this can be done by modifying the filter assignments, clicking on the channels table for each UHF input and then deselecting the unwanted channels.

How to use the ASuite app to configure the SmartKom amplifier

To add a channel that is being received better through another input, or even a channel generated by a modulator, the user simply has to click on the channels table for that UHF input, then select the new channels to be added.

Powering through the cable can be activated by clicking on the DC option from the table for each input. The following power options are available: force sending to 12V, automatic management, or deactivate.

How to use the ASuite app to configure the SmartKom amplifier

Managing the output level

Depending on the installation situation, it may be necessary to change the output level. This is done by clicking on the “Level” button, then selecting one of the available values.

The maximum output level that can be selected for the SmartKom is 85dBµV.

Adjusting the equalization

Properly adjusting an installation usually requires adjusting the equalization for the channels and compensating for the attenuation differences that can affect channels at different frequencies. On the adjustment screen, the channels are represented visually and the user can adjust their levels using the arrows appearing over each of them.

How to use the ASuite app to configure the SmartKom amplifier

Finalizing and sending the configuration

After all desired changes and adjustments have been made, the configuration must be sent to the SmartKom. This is done by clicking on the “Send” button, which is represented by an up arrow icon. We also recommend always saving the configuration on the mobile device, by clicking on the floppy disk icon. This helps the user save lots of time later by easily recovering the configuration to reuse on other SmartKom devices in the zone, simply by clicking on the file folder icon.
