Baseband Up-Conversion to Desired Intermediate Frequency
Application Notes
Comparing Different Up-Conversion Methods
New generations of communication applications – such as radar, communication systems, or electronic warfare and SIGINT equipment – need to be tested as realistically as possible, to ensure a strong foundation for reliable transmission. Realistic signal scenarios that simulate transmission, including interference, fading and more, can push designs to the limit while reducing test costs, by minimizing the need for the high cost of flight-testing.
Critical needs are
– Getting the best signal quality in the desired frequency range,
– Having the flexibility to simulate the different real-world distortions, and
– Long playtime for different signal scenarios.
This means the modulation bandwidth needs are constantly increasing. At the same time, excellent signal fidelity remains as necessary as ever, and distortions have to be kept to a minimum.
