Raltron Released RXF Monolithic Crystal Filter Series
The new filter series targets low-insertion-loss requirements in LEO satellite broadband ground hardware.
Updated on Oct. 14, 2026 in Semiconductors
Raltron has introduced the RXF monolithic crystal filter series designed to support signal integrity in high-frequency applications. These components are intended for use in LEO satellite ground stations and related networking equipment.
Why it matters
As LEO satellite constellations expand, ground segment infrastructure requires increasingly compact and frequency-stable components. These filters address those specific constraints in user terminals and gateway stations.
The series includes the RXF-100.000-20-6035-6-4 and RXF-150.000-15-7050-6-2 models. Both units provide controlled frequency response and low insertion loss to preserve signal strength across RF and intermediate-frequency paths.
The players
Raltron
A manufacturer of frequency management devices, including crystal oscillators, filters, and resonators for high-performance communications hardware.
The details
Monolithic crystal filters are passive components that use the piezoelectric effect—the generation of electrical charge in response to applied mechanical stress—to create precise band-pass frequency characteristics. By integrating these into compact packages, the design reduces signal attenuation in satellite ground equipment, such as flat-panel antennas and phased-array systems. These subsystems rely on strict signal filtering to differentiate satellite transmissions from terrestrial noise.
Timeline
Raltron introduced the RXF monolithic crystal filter series on October 14, 2026.
The Tech Race
The RXF series addresses the specific frequency management needs of current LEO satellite broadband ground equipment. It follows the industry-wide push for smaller, high-frequency components that can support the rapid scaling of satellite-to-ground communication networks.
The technology is intended for engineers and developers building LEO satellite ground terminals, gateways, and networking systems. Implementation of these filters will improve signal integrity in next-generation broadband hardware.
The takeaway
Reliable frequency filtering is critical to the efficiency of the growing LEO satellite ecosystem. Engineers should monitor for additional technical documentation on these filters, specifically insertion loss and temperature performance benchmarks, to assess suitability for specific array designs.
