Why FR4 Ruined Your S-Band Filter: Cross-Coupled Topologies on Rogers Substrates
Designing a high-performance downconverter can be tough. You need sharp filtering, but this often leads to high signal loss, which hurts your system’s sensitivity. It feels like a trade-off you can’t win. To optimize an S/C band downconverter filter, you must combine a low-loss substrate material, like Rogers, with an advanced filter topology1. A cross-coupled […]
Cracking Satellite Converter Linearity: Master Cavity Design and OIP3 Optimization
Achieving high linearity in satellite converters feels like a constant battle. Poor designs cause signal interference and performance drops. The solution is often found in the cavity design itself. A high-linearity bidirectional satellite converter absolutely depends on its cavity design. This physical enclosure provides essential shielding to prevent signal leakage and is carefully dimensioned to […]
