Product overview
The R&S®CMX-RF42 is the most compact active device in its class, built for 5G FR2 (millimeterwave) measurements. It combines, amplifies and attenuates RF signals from several sources across the mainstream 3GPP FR2-1 bands (n257 to n261). Connected to an R&S®CMXHEAD series radio head such as the R&S®CMXHEAD30, it enables advanced test scenarios such as interband carrier aggregation. High-performance amplifiers in both the TX and the RX direction expand the dynamic range well past what the 3GPP specification demands, supporting the complete test flow from early development through to final certification and regulatory compliance.
Key features
- Wideband, multi-band capability: covers all the mainstream 3GPP FR2-1 bands (n257 to n261) and combines carriers from several bands into a single input stream for the feed antenna of an FR2 test chamber, which makes interband carrier aggregation testing possible.
- Wide dynamic range: high-performance amplifiers in the TX and RX directions improve the dynamic range of advanced 5G millimeterwave measurements considerably. The extra headroom goes beyond the 3GPP specification and supports more demanding test scenarios.
- More downlink power and better uplink sensitivity: the expanded dynamic range delivers higher downlink performance and stronger uplink sensitivity for validating next-generation FR2 RF designs.
- The most compact active device in its class: multi-source signal combining, amplification and attenuation in one compact housing that is easy to integrate.
- Seamless integration with the CMX500: designed to extend the FR2/FR2-1 measurement capability of the R&S®CMX500 5G one-box signaling tester, used with CMXHEAD series radio heads such as the R&S®CMXHEAD30.
- Coverage across the whole flow: a complete 5G FR2 RF design test solution from early development through to final certification and regulatory compliance testing, with dependable measurement results.
Typical applications
- 5G mmWave development testing: early development validation of next-generation 5G FR2 RF designs, with dynamic range headroom beyond the specification for demanding test scenarios.
- Interband carrier aggregation (interband CA): combines carriers from the low, mid and high FR2-1 bands into a single stream for an OTA test chamber, supporting 5G Advanced carrier aggregation testing.
- OTA conformance testing: used with an R&S®ATS800R or R&S®ATS1800C OTA test chamber for 3GPP/CTIA conformance and regulatory compliance testing.
- Millimeterwave OTA measurements: works with the R&S®CMX500 and CMXHEAD series radio heads to perform accurate 5G FR2 over-the-air (OTA) measurements.
- Certification and regulatory compliance verification: provides the full FR2 RF test capability needed from product development through to final market certification, meeting the regulatory requirements of each region.
