R&S NRP90S(N) power sensors for RF power measurements up to 90 GHz

1 min read

Rohde & Schwarz, currently the only supplier of fast diode sensors for power measurements up to 67 GHz, has announced that it is increasing the maximum measurable frequency of its diode power sensors to 90 GHz.

This is higher than any other diode sensor currently available and this technology will enable extremely fast and accurate power measurements with the highest sensitivity from a compact and light-weight portable instrument.

High speed power measurements are now possible for all frequencies above 67 GHz in 5G, automotive radar and satellite communications applications including the entire E band.

The NRP90S and NRP90SN power sensors from Rohde & Schwarz provide a significantly improved level of performance in power measurements. The new instruments combine a frequency range of 50 MHz to 90 GHz with a dynamic range from -70 dBm to 20 dBm along with high measurement speeds of 50,000 measurements per second.

Compared to current thermal power sensors for measurements over 67 GHz, the diode technology increases the power measurement dynamic range by 35 dB and significantly cuts test times.

By extending the maximum frequency from 67 GHz to 90 GHz, these new sensors can cover the latest spectrum allocation for 5G FR2-2 up to 71 GHz, satellite communications in both the 71 GHz to 76 GHz band and the 81 GHz to 86 GHz band, automotive radars operating from 76 GHz to 81 GHz, as well as other lower frequency wireless transmission technologies.

The combination of a portable form factor and flexible operating modes has made these R&S NRPxxS power sensors suitable for both local and remote installation in maintenance or monitoring applications.

Users benefit from maximum operating flexibility. The power sensors can be connected to an R&S NRX power meter, selected Rohde & Schwarz signal generators and analysers, or a PC with the R&S NRPV virtual power meter installed. The devices support the USBTMC protocol industry standard for easy integration into test systems. The R&S NRPxxSN also includes an Ethernet interface to support remote LAN operation.
