Our PROFILANT TETRA couplers were developed with the aim of guaranteeing the greatest possible operational reliability for safety-critical radio applications.
The latest technology enables compliance with all ETSI-relevant parameters:
- Developed for the extended TETRA BOS Band A+: UL: 380-386.5 MHz DL 390-396.5 MHz.
- Large-signal-proof thanks to the built-in bandpass duplex filter.
- > 70dB insulation ensures operational safety even at higher power levels.
- Focus on lowest insertion loss
