Product overview
The R&S®CMXHEAD50 is the next generation broadband remote radio head for signaling, offering bidirectional testing across the complete 5G mmWave (FR2-1) range. It is the only remote radio head on the market that covers the full 21.84 GHz to 50.2 GHz range while delivering EVM performance down to 0.5% / -46 dB. The R&S®CMXHEAD50-Evo adds a high-quality dual LO synthesizer and an extra sensitive low-noise RX port that widens the dynamic range. Up to four units can be combined with R&S®CMX-RF42E active mmWave frontend modules to build a high-performance multi-carrier test solution.
Key features
- Full frequency coverage from 21.84 GHz to 50.2 GHz, across every 5G NR FR2-1 band
- Outstanding EVM performance: -46 dB / 0.5% in both the TX and the RX direction, with no extra external equipment
- Dual LO architecture: the TX and RX paths are optimized independently for the best RF signal quality
- Extra sensitive low-noise RX port lifts receive sensitivity considerably for a very wide dynamic range (Evo version)
- Integrated mmWave RF switch matrix simplifies the test setup and supports switching between paths
- External LO input ports suit advanced measurements that need precise frequency synchronization
- Modular expansion: up to four units work together with the R&S®CMX-RF42E for multi-carrier aggregation testing
Typical applications
- Signaling tests of 5G NR FR2 mmWave devices (handsets, modules, chipsets)
- Development and validation of Ka band communication systems
- Interband carrier aggregation test scenarios
- Over-the-air (OTA) measurements
- Design validation and conformance testing of 5G mmWave wireless products
