SAW filters for GNSS applications help manufacturers resolve supply chain concerns

Raltron offers specific SAW Filters for GNSS navigation systems that optimise performance and supply a viable second source alternative for other mainstream suppliers.

The RSF Series of SAW filters is specifically designed for GPS, GLONASS, Galileo, Compass (BeiDou) and soon NavIC systems. Developed to aid system engineers in optimising performance in GNSS applications, the filters minimise insertion losses and ripple and deliver superior signal attenuation outside the useful bandwidths with competitive temperature behaviour. The filters can efficiently separate or combine signals of different frequencies, allowing the receiver to simultaneously function with various satellite signals.

The company's engineering services also assist design engineers in handling SAW filter integration challenges, including impedance matching, low noise, interface compatibility and space constraints. The family of SAW Filters fulfils design needs for very small chip size packages, providing the standard industry dimensions down to 1.1mm x 0.9mm.

"Our SAW filters' compact size and ability to withstand higher power levels, combined with our ability to fine-tune them for specific customer requirements, make them ideal for use in today's GNSS receivers and other devices," said Sasha Wolloch, president of Raltron. "We are also in development of SAW filters that operate in the L5 and S bands for the NavIC system in India."

The company's IoT, commercial, and automotive grade SAW filters help integrate GNSS applications with other devices.
