Over-the-Air Power Measurement

The Rohde & Schwarz NRPM OTA power measurement solution for 5G and wireless gigabit components. enables users working in development and production to calibrate the output power of the antenna on a DUT and to test the DUT's beamforming function. The solution works in the frequency range from 27.5 GHz to 75 GHz and therefore covers the 28 GHz band currently being discussed for 5G as well as the frequency range from 55 GHz to 66 GHz for WLAN in line with IEEE 802.11ad and frequencies above 66 GHz in line with IEEE 802.11ay.

The solution consists of two core components: the antenna module and the three-channel sensor module. The R&S NRPM A66 antenna module is a simple, polarized Vivaldi antenna with an integrated diode detector for power measurements. Thanks to its high linearity, it measures the relative power with a measurement accuracy better than 0.2 dB. Because the power is measured directly on the antenna, the user does not need any additional RF cables, which also eliminates complex compensation for cable loss. With a single antenna module, the user can calibrate the output power on a DUT, for example. With several spatially offset antenna modules, it is possible to test a DUT's beamforming function.

The R&S NRPM3 three-channel sensor module processes measurements from up to three antenna modules. If more than three antennas are needed for a test setup, users can operate any number of sensor modules in parallel. The additional measurement points increase the measurement resolution during beamforming tests.
