Key facts
More dynamic range, full frequency coverage and excellent EVM performance
The R&S®CMXHEAD50 is the only remote radio head for signaling that offers bi-directional testing at five mmWave frequency bands and additional EVM booster ports - all within one hardware set. It covers all 3GPP frequency bands in FR2-1 between 22 and 50 GHz: n257, n258, n259, n260, n261 and even the new n262 frequency band that features 1000 MHz of bandwidth between 47.2 and 48.2 GHz. With active mmWave combiners from R&S up to four R&S®CMXHEAD50 can be combined to enable advanced scenarios such as interband carrier aggregation 28 GHz + 39 GHz.
Leading multi-band capabilities
The R&S®CMPHEAD50 is the only RRH that supports all 3GPP frequency bands in FR2-1 in combination with individual external local oscillator (LO) inputs for both RX and TX.
All FR2-1 frequency bands are covered
Optimized for low power levels
The standard TX and RX ports already have impressive EVM performance over a wide range of power levels, but the new low-noise RX port improves sensitivity to a whole new level.
High dynamic range (HDR) for FR2 testing
For best RF performance in TX and RX direction
Both downlink and uplink paths use separate local oscillators to ensure the best RF signal quality in the TX and RX directions. The R&S®CMXHEAD50 is the only RRH for full UE testing that supports all 3GPP frequency bands in FR2-1 in combination with individual external local oscillator (LO) inputs for both RX and TX. This enables further EVM performance improvements for cutting-edge RF measurements.
