Raltron has introduced its RXF series of monolithic crystal filters for ground-based equipment used in low Earth orbit (LEO) satellite broadband networks. The two filters, operating at 100 MHz and 150 MHz, are designed to provide stable frequency response and low insertion loss in compact packages for outdoor communication systems. For eeNews Europe readers developing satellite communication hardware, the monolithic crystal filters address RF filtering requirements in user terminals and gateway infrastructure. Their compact design and resistance to demanding environmental conditions could be useful for equipment operating continuously in LEO broadband networks. Crystal filters for satellite ground equipment The RXF series comprises two models: RXF-100.000-20-6035-6-4 and RXF-150.000-15-7050-6-2 . The devices operate at nominal frequencies of 100 MHz and 150 MHz, respectively, and are intended for applications requiring controlled frequency response in RF and intermediate-frequency (IF) signal paths. According to Raltron, the RXF filters are designed to maintain low insertion loss and stable filtering characteristics across their specified operating conditions. The company also highlights their compact footprint, which is intended to help engineers meet size, weight and power (SWaP) constraints in satellite ground equipment. Supporting user terminals and gateway stations The monolithic crystal filters are intended for several types of LEO satellite broadband infrastructure. These include customer-premises equipment using phased-array or flat-panel antennas, gateway antenna systems and ground stations, and networking and control subsystems requiring stable signal paths. In such applications, crystal filters can provide frequency selectivity in receiver and IF chains, helping suppress unwanted signals before subsequent amplification, conversion or processing stages. The devices are positioned for ground-based systems supporting Ku- and Ka-band satellite networks, rather than direct filtering at those microwave frequencies. “As providers scale LEO satellite broadband networks, the user terminals and gateway ground stations connecting subscribers to those constellations must deliver increasingly stable RF performance across Ku- and Ka-band frequencies under continuous-duty outdoor conditions,” said Sasha Wolloch, President of Raltron. Compact filtering for LEO infrastructure The RXF series extends Raltron’s frequency-control portfolio into filtering applications associated with growing LEO broadband infrastructure.
