IQFR2-RU: Next-Generation 5G FR2 O-RAN Radio Unit Tester

The IQFR2-RU is LitePoint’s next-generation, fully integrated test solution for validating and production testing of 5G FR2 O-RAN Radio Units (O-RUs). Purpose-built for mmWave (FR2) radio performance, IQFR2-RU combines 3GPP 5G NR RF measurements with complete O-RAN C/U/M/S-plane functionality, enabling seamless configuration and control of O-RUs under test.

As networks evolve toward open and interoperable architectures, O-RAN introduces new challenges for radio validation. IQFR2-RU addresses these challenges with a single-box platform that integrates RF testing and fronthaul emulation—eliminating the need for external DU emulators and reducing setup complexity.

Why IQFR2-RU?

• Purpose-Built for mmWave: Designed for FR2 frequencies (23 GHz – 45 GHz) with up to 1.7 GHz instantaneous bandwidth, supporting carrier aggregation and advanced beamforming
• Single-Chassis Integration: Combines RF generation, analysis, optical fronthaul interface, and routing in one factory-calibrated unit
• RAN Ready: Implements split option 7.2x with full C/U/M/S-plane messaging and eCPRI packet waveform playback for both uplink and downlink
• Accelerated Time-to-Test: Reduces setup time from hours to minutes, enabling rapid deployment in R&D and production environments
• Future-Proof Design: Supports evolving O-RAN and 5G NR specifications for long-term scalability

Key Highlights

• Integrated VSG/VSA Architecture: Vector Signal Generator and Analyzer for FR2 waveform generation and analysis
• Advanced RF Measurements: Power, TPDR, TOOP, frequency error, EVM, TAE, OBW, ACLR, OBUE, sensitivity, dynamic range, ACS, IBB, receiver intermodulation, ICS and OTA beamforming performance
• High-Precision Timing: IEEE 1588 PTP / SyncE support with optional 1PPS and 10 MHz reference outputs
• Scalable Architecture: Ideal for both R&D labs and high-volume manufacturing, minimizing cost of test (COT)
• Comprehensive Protocol Support: Handles O-RAN fronthaul messaging and regression testing for C/U/M/S-plane

Target Applications

• RU RF Performance Validation: Power, frequency error, EVM, ACLR, sensitivity
