Product overview
The R&S®CMX-RF42E is the most compact active RF frontend in its class, built for 5G FR2 millimeterwave measurements and extending the measurement frequency of the R&S®CMX500 to 50 GHz. It aggregates the signals of up to four R&S®CMXHEAD50 remote radio heads across the full 21.84 GHz to 50.2 GHz range and covers every 3GPP FR2-1 band from n257 to n262. Highly linear, low-noise amplifiers in both the TX and RX direction raise the system dynamic range and signal-to-noise ratio (SNR) considerably, delivering higher downlink performance and stronger uplink sensitivity than the 3GPP specification requires. It also supports interband carrier aggregation (interband CA), making it a complete solution from early development validation through to final certification and regulatory compliance testing.
Key features
- Full FR2-1 coverage up to 50 GHz: the complete 21.84 GHz to 50.2 GHz range and every 3GPP FR2-1 band (n257, n258, n259, n260, n261, n262), the Ka band for non-terrestrial networks (NTN) included, gives millimeterwave devices full test coverage.
- Multi-head signal aggregation: aggregates the TX/RX signals of up to four R&S®CMXHEAD50 or CMXHEAD50-Evo remote radio heads, combining, amplifying and attenuating RF signals from several sources for advanced test scenarios such as interband carrier aggregation.
- Much wider dynamic range and better SNR: highly linear, low-noise amplifiers in the TX and RX directions expand the system dynamic range and improve SNR across the whole range, delivering higher downlink performance and stronger uplink sensitivity than the 3GPP specification requires.
- Interband carrier aggregation (interband CA): combines carriers from the low, mid and high FR2-1 bands into a single input stream for interband carrier aggregation testing, supporting 5G Advanced multi-carrier scenarios.
- The most compact active device in its class: multi-source signal aggregation, amplification and attenuation in one compact housing that integrates easily into an OTA test chamber setup such as the R&S®ATS800R.
- Coverage across the whole flow: from early development validation through to final regulatory certification (3GPP TS 38.521), with full 5G FR2 RF test capability for EIRP, EIS, TRP and CDF measurements to meet the regulatory requirements of each region.
Typical applications
- 5G mmWave development testing: early development validation for next-generation 5G FR2 RF designs, with dynamic range headroom beyond the specification for demanding millimeterwave test scenarios.
- Interband carrier aggregation (interband CA) testing: aggregates carriers from the low and high FR2-1 bands into a single stream for the feed antenna of an OTA test chamber, supporting 5G Advanced carrier aggregation scenarios.
- 3GPP conformance and regulatory compliance testing: used with an R&S®ATS800R or R&S®ATS1800C OTA test chamber to run EIRP, TRP and CDF measurements to 3GPP TS 38.521 for certification and regulatory requirements.
- Millimeterwave OTA measurements: works with the R&S®CMX500 and CMXHEAD50 series remote radio heads to run accurate 5G FR2 over-the-air (OTA) measurements.
- Ka band non-terrestrial network (NTN) testing: Ka band measurement support for FR2 RF performance validation of satellite communication and non-terrestrial network (NTN) devices.
