SAF Tehnika Launches PhoeniX IRFU Mk3: Compact, Very High Power Indoor Radio Frequency Unit

SAF Tehnika is proud to announce the launch of the PhoeniX IRFU Mk3, the next-generation indoor radio frequency unit designed to deliver high performance, energy efficiency, and operational flexibility in a compact 1U rack-mountable chassis.

Building on the success of last year’s PhoeniX ODU Mk3, which set a new standard for compact size and power to price ratio, the PhoeniX IRFU Mk3 brings the same philosophy indoors, engineered to do more while using less.

Solving Critical Indoor Deployment Challenges

As operators face increasing demands for high-capacity, energy-efficient indoor radios, the new PhoeniX IRFU Mk3 addresses these challenges with:

  • High Transmitter Output Power: +33 dBm at 4QAM ensures reliable, high-capacity connections even with long RF feeder cables.
  • Energy-Efficient Design: Fanless design and reduced power consumption extend operational lifetime, eliminating moving parts and dust cleaning schedules.
  • Wide Bandwidth Support: 1.75 MHz – 112 MHz channel options accommodate diverse capacity and spectrum requirements.
  • Compact & Rack-Mountable: 19” rack-mountable, 1U high chassis optimizes space utilization in indoor deployments.
  • High Throughput & Modulation: Supports up to 4096QAM (depending on the modem), maximizing spectral efficiency and data rates.
  • Optimized Signal Quality: Digital Pre-Distortion (DPD) improves linearity and reduces distortion for stable transmission.
  • Flexible Deployment: 2 x SMA connectors for Tx and Rx support external filters; dedicated control port enables full-redundancy setups.

The new PhoeniX IRFU Mk3 is ideal for operators seeking a high-performance, energy-efficient indoor RF solution that integrates seamlessly into existing network infrastructure while offering future-ready capabilities.

“PhoeniX IRFU Mk3 delivers better performance in a smaller, more energy-efficient package, enabling operators to expand indoor network capacity without compromise. Following the footsteps of PhoeniX ODU Mk3's success in outdoor deployments, this IRFU unit continues our mission to engineer solutions that do more with less,”
said Toms Kalderovskis, Head of Product Development at SAF Tehnika.

Availability

PhoeniX IRFU Mk3 is available immediately through SAF Tehnika distribution partners, initially supporting L6 and U6 GHz, with additional bands to follow. For more information, visit PhoeniX IRFU Mk3 product page.
