Precision RF Integration – Our Ethos 

In everything we do we aim for the highest levels of precision, This is especially true of our system specification and design methods. In the satellite industry the word ‘precision’ is synonymous with ‘expensive’. At iSat We think differently. We think that precision should provide value not extra expense, so we approach our terminal design with this in mind.

We pay attention to every fraction of every dB of loss and gain in every single component we use. One benefit of this is that we can minimise the amount of amplifier power needed to fit your link budget.

The amplifier will usually be the highest cost item within a system. Being able to specify and mitigate system losses accurately before purchase could mean the difference between buying a 10Watt or a 20Watt amplifier. Based on average industry pricing this is likely to mean a saving of thousands per antenna system. Look at our example below:

Insertion Loss (dB)

These excerpts are from the datasheets of an X-band filter made by a well-known manufacturer and the filter that we use. This is a good example of variations in performance across a range of products which perform the same job. By paying close attention to these performance figures and selecting the best components during system design, we can minimise system losses. Recovering even 1dB of gain within the antenna system can easily translate to a step down in the size of amplifier needed. Put simply, spending a little bit more on an expensive filter could save a relative fortune in amplifier costs!
