OmProtec®-RBF MF-05 HP-02 – High-Performance High-Pass Filter in a Compact Design
With the OmProtec®-RBF MF-05 HP-02 filter, Antonics introduces an innovative high-pass filter that delivers exceptional performance despite its compact size. This small yet powerful component integrates seamlessly into antenna systems and is specifically engineered for use in rail and road vehicles, where interference-free signal transmission is critical.
Technology for Interference-Free Communication
The OmProtec® filter reliably blocks unwanted signals in the DC to 960 MHz range, delivering a stopband attenuation of 40 dB to ensure clean separation between operational and interfering frequencies. Thanks to an excellent return loss of –14 dB and a typical VSWR of 1.5:1, the filter creates optimal conditions for clear, interference-free signal transmission—perfectly matched to Antonics antenna systems. With an insertion loss of just 0.8 dB, the signal quality is preserved across the entire passband from 600 to 4000 MHz with minimal power loss.
Applications and Advantages
The OmProtec® filter is ideal for communication systems in trains and vehicles where precise frequency filtering is required.
It has been developed based on TE-ANT, an antenna specification created by a consortium of vehicle manufacturers. This specification addresses the need to decouple safety-relevant radio systems both from each other and from infotainment systems. In combination with Antonics antennas, this filter enables isolation levels of up to 80 dB between WLAN and GSM-R.
Its simple installation using four M2 threaded mounting points makes the filter easy to deploy, while compliance with standards such as EN 50155, EN 45545-2, and IEC 60068 underscores its reliability and safety in demanding environments.
Compact, Rugged, and Versatile
The filter’s compact dimensions—only 40 × 20 × 20 mm—and lightweight design (just 80 g) allow for easy integration into a wide variety of applications. With an IP54 rating, it is protected against dust and splashing water. The wide operating temperature range of –40 °C to +85 °C ensures dependable performance even in extreme environmental conditions.
Future-Proof and Efficient
With a maximum input power of 10 W and a 50 Ω impedance, the high-pass filter is a forward-looking component for modern communication infrastructures. It ensures interference-free transmission, enhancing the safety and stability of wireless systems.
