SAF Tehnika Launches PhoeniX IRFU Mk3 to Deliver High Power and Energy Efficient Indoor RF Performance

(IN BRIEF) SAF Tehnika has launched the PhoeniX IRFU Mk3, a next-generation indoor radio frequency unit designed to meet the increasing demand for high-capacity and energy-efficient network infrastructure. The compact 1U rack-mounted device delivers high transmitter power, wide bandwidth support, and advanced modulation capabilities, enabling reliable and high-performance communication even in complex indoor environments. Its fanless, energy-efficient design reduces maintenance needs and operational costs while extending product lifespan. Additional features such as Digital Pre-Distortion for improved signal quality and flexible connectivity options make it suitable for integration into existing systems and future network expansion. Available immediately with support for key frequency bands, the PhoeniX IRFU Mk3 represents a significant step forward in indoor RF technology, offering operators a powerful and scalable solution for modern network demands.

(PRESS RELEASE) RIGA, 23-Apr-2026 — /EuropaWire/ — SAF Tehnika has introduced the PhoeniX IRFU Mk3, a new indoor radio frequency unit designed to deliver high power, efficiency, and flexibility within a compact rack-mounted format. The latest addition to the PhoeniX product family builds on the company’s established approach of maximizing performance while minimizing size and energy consumption, extending these principles from outdoor to indoor deployments.

Housed in a 1U, 19-inch rack-mountable chassis, the PhoeniX IRFU Mk3 is engineered to address the growing demands faced by network operators for higher capacity and more energy-efficient indoor radio solutions. The unit offers a high transmitter output power of +33 dBm at 4QAM, enabling stable and reliable connections even when long RF feeder cables are required. This capability supports consistent performance in complex indoor network environments.

A key focus of the design is energy efficiency and operational simplicity. The fanless architecture reduces power consumption and eliminates moving parts, which in turn minimizes maintenance requirements such as cleaning and servicing. This approach contributes to longer operational lifetimes and lower total cost of ownership, particularly in demanding deployment scenarios.

The system supports a wide bandwidth range from 1.75 MHz to 112 MHz, allowing operators to adapt to varying spectrum availability and capacity requirements. In addition, it enables high data throughput through support for advanced modulation schemes of up to 4096QAM, depending on the modem configuration. Integrated Digital Pre-Distortion technology enhances signal quality by improving linearity and reducing transmission distortion, ensuring stable and efficient communication.

Flexibility in deployment is another core feature of the PhoeniX IRFU Mk3. The unit includes dual SMA connectors for transmit and receive functions, supporting the use of external filters, as well as a dedicated control port that enables full-redundancy configurations. These features allow seamless integration into existing network infrastructure while preparing operators for future scalability.

Toms Kalderovskis emphasized that the new unit delivers enhanced performance within a smaller and more energy-efficient footprint, enabling operators to expand indoor network capacity without compromise. He noted that the product continues the company’s commitment to engineering solutions that optimize both performance and resource usage.

The PhoeniX IRFU Mk3 is available immediately through SAF Tehnika’s distribution network, initially supporting L6 and U6 frequency bands, with additional bands planned. The launch reflects the company’s ongoing focus on delivering advanced microwave communication solutions, building on more than 25 years of experience serving customers in over 130 countries.

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.
