SAW filters for GNSS applications - Raltron

November 23, 2023

The RSF Series of SAW filters is specifically designed for GPS, GLONASS, Galileo, Compass (BeiDou) and soon NavIC systems. Developed to assist system engineers optimize performance in GNSS applications, the RSF SAW filters minimize insertion losses and ripple and provide superior signal attenuation outside the useful bandwidths, with competitive temperature behavior. The RSF SAW filters can be used to efficiently separate or combine signals of different frequencies, enabling the receiver to operate with various satellite signals simultaneously.

Raltron’s engineering services also help design engineers handle SAW filter integration challenges including impedance matching, low-noise, interface compatibility and space constraints. The family of RSF Series SAW Filters meets design requirements for very small chip size packages (CSP) providing the standard industry dimensions down to 1.1 mm x 0.9 mm.

Their SAW filters have a compact size and ability to withstand higher power levels, combined with the ability to fine tune them for specific customer requirements. That makes them ideal for use in today’s GNSS receivers and other devices. Raltron IoT grade, commercial grade, and automotive grade SAW filters help with integration of GNSS applications with other devices.

Raltron’s extensive SAW Filter family is ideal for applications including smartphones, tablets, wireless sensors, automotive, base station, RFID, military radar, IoT, wearable technology, drone devices and smart appliances and more.
