Product overview
The R&S®NRPM is a fully calibrated, scalable over-the-air (OTA) millimeterwave power measurement solution covering 18 GHz to 90 GHz, designed for 5G FR2, satellite payloads, beamforming verification and antenna array characterization. Where a cabled measurement at millimeterwave frequencies would lose a great deal of signal to transmission loss, the NRPM picks the power up over the air with a high-sensitivity diode detector integrated into the antenna module itself, and its very low radar cross section (< −26 dB/sm) suits it to a benchtop setup or an anechoic chamber.
Key features
- Full millimeterwave coverage from 18 GHz to 90 GHz
- Calibrated across the whole range, in an OTA power measurement architecture you can scale one module at a time
- The diode detector sits inside the antenna module, which shortens the signal path and cuts loss
- Very low radar cross section (typ. < −26 dB/sm), about 15 dB below a conventional horn antenna
- Single-polarized (A90) and dual-polarized (A90D) antenna modules
- Three-channel sensor module measures several beams at once, over USB or LAN
- 2.2 μs rise and fall time, for pulse and trace measurements
Typical applications
- OTA power verification of 5G FR2 millimeterwave base stations and terminals
- Beamforming and beam steering characterization
- Calibration and characterization of phased array antennas
- Transmit power measurements on satellite payloads and ground terminals
- IEEE 802.11ad / 802.11ay (WiGig) RF conformance testing
- Transmit power calibration of automotive millimeterwave radar sensors
