Aicox is part of the consortium of companies led by Integrasys to coordinate the “RF Interference Removal for Military Services based on Spaces Link”

The European Commission is supporting R&D projects through the program European Defence Fund (EDF) 2021, with almost €1.2 billion for Defence and R&D projects. INTEGRASYS has been selected as one of the companies for obtaining multiple EDF programs, and two projects, thanks to its defence expertise acquired over the years.

Integrasys will be coordinating RFSHIELD “RF Interference Removal for Military Services based on Spaces Link”. The project will take up to 30 months, until June 2025. RFSHIELD will ensure the protection of the SatCom services from intentional and non-intentional interferences, increasing the availability and performance of COMSATCOM/MILSATCOM services for military users. The reason why INTEGRASYS has been designated as coordinator is due to the current expertise that the company has in Interference Removal solutions, with its available CLEANRF product. The consortium of the project is formed by 5 companies, AICOX, MBS, and INGESPACE as INTEGRASYS’ partners, who are also specialized in defence capabilities.

The company has also been awarded NAUCRATES project, which is focused on microsatellites for Geostationary Orbit Surveillance and Intelligence. The project duration will be until December 2025, and the main goal is to design and demonstrate a microsatellite with less than 100kg mass, positioned in a stable orbit outside the GEO belt, as an in-orbit optical sensor with the capability to approach other objects in GEO to take centimetre level resolution images.

Integrasys is highly-oriented to defence solutions as the company is committed to contributing to innovation in this dynamic sector, so EDF 2021 is one of the multiple defence initiatives. “‘’We are very honoured to support defence with the rising threats from more allies nations and we look forward to supporting more missions in the future’’, says Alvaro Sanchez.

GaN amplifier technology has had a real impact on Block Upconverter and SSPA design for Satcom applications. And it’s a hot buzzword in the industry.

Terrasat have implemented GaN into several IBUC models where it is perceived to deliver benefits for customers. It brings advantages:

  • higher power density– delivering higher power in a smaller, lighter enclosure.
  • Reduced power consumption.
  • Cost reduction in some frequency band–output power combinations.

Terrasat Engineers have implemented techniques to compensate for the inherent nonlinearity of GaN devices. This has resulted in a significant reduction in the amount of output power back-off required to meet the MILSTD definition of Linear Power (PLin) which is the useable output power and standard for comparing BUC/SSPA output power performance.

…significant reduction in the amount of output power back-off required to meet the MILSTD definition of Linear Power (PLin)…

 

 

 

 

 

Limitations that Deserve Respect

All technologies have their strengths and limitations. It is as important to understand the limitations as it is to know the advantages. With GaN devices, limitations can become evident in operations using more than one carrier. This is not to say that it cannot be used with multiple carriers. But GaN performs differently than GaAs or TWTA amplifiers with respect to multicarrier operation. There are two situations where this limitation should be respected.

First, with a GaAs amplifier, you typically see a relatively linear and continuous IMD3 improvement with output power back-off. Below in Graph A is an IMD3 plot for a 200W C IBUC R GaAs amplifier. (The purple line is the -22 dBc IMD3 part of the MIL-STD linearity definition).

GaN & GaAs Challenges

You can see from this plot that IMD3 with a GaAs amplifier decreases rapidly and in a fairly strong correlation to an increase in output power backoff.

With a GaN unit there is a different result. Please see the IMD3 plot below of a 200W Full Ku IBUC G GaN unit. Things start out fine, but the curve quickly starts to flatten. Then at about 6 dB back-off it hits a “floor”. It doesn’t get any better. This is a characteristic of GaN devices that cannot be overcome.

What this means is that there is a limitation to the quantity of carriers that can be accommodated.

The second limitation is a bit scarier. It only shows up in situations with widely separated carriers. By the MIL-STD definition, all manufacturers measure IMD at a 5 MHz offset for specifications shown on the data sheet. Graph C shows IMD products at wider offsets.

The red line is the defined -22 dBc IMD level. The other lines plot IMD above and below the test channels at saturated power and then with 1 dB of output power back-off. At the 5 MHz offset there is clearly no problem meeting the -22 dBc requirement. However, this shows how the intermodulation products are increasing in intensity as the carrier offset increases. Whereas logic from working with amplifiers would say that the further two carriers are from each other, the less they will interact, it turns out that the opposite is true with GaN devices. With carriers spaced more than 25 MHz apart, there will be intermodulation products that may interfere with other services.

GaN technology, when implemented well, can provide many benefits in terms of size, weight, and power consumption

At Terrasat we strive to enable our customers to make informed decisions. One thing we do not want is for any of our customers to learn the facts only after they install and commission their terminal. As a general statement Terrasat Engineering advises caution in planning carrier spacing greater than 20 MHz.

In summary, GaN technology, when implemented well, can provide many benefits in terms of size, weight, and power consumption. It is prudent to take the multi-carrier limitations into consideration when determining what BUC to invest in for a site.

Please note that the manufacturers of the GaN devices are working on a next generation of devices that will mitigate these limitations. This information is applicable to GaN amplifiers available as of this writing and we look forward to improvements.
