RF Filters and Band Rejection Filters for GSM-R, FRMCS, 5G and LTE

Reliable RF Filter Solutions for Railway, Bus and Vehicle Communication

The increasing digitalization of modern transport networks places high demands on the electromagnetic compatibility of communication systems. Different radio standards such as GSM-R, FRMCS, 5G, LTE, WLAN and TETRA are now frequently operated simultaneously within a single vehicle or infrastructure platform. Without suitable RF filters, interference and disruptions can occur in safety-critical communication systems.

Antonics develops high-performance RF filters and band rejection filters for use in rolling stock, buses and critical communication infrastructures. Our filter solutions enable the reliable coexistence of different radio technologies while protecting sensitive communication systems against unwanted interference signals.

Highly selective band rejection filters are becoming increasingly important, particularly in the course of the migration from GSM-R to FRMCS. They help protect safety-relevant railway communication services from interference caused by public mobile networks and 5G services.

The product portfolio includes:

  • GSM-R band rejection filters
  • FRMCS filter solutions
  • 5G coexistence filters
  • Band-pass filters
  • DC blockers
  • Customized RF filter solutions

Antonics OmProtec® filters are characterized by high rejection attenuation, low insertion loss and robust mechanical properties for demanding railway and vehicle applications. The solutions comply with relevant standards such as EN 50155, IEC 61373 and EN 45545-2 and support reliable and future-ready vehicle communication.
