Power Sensors for RF Power Measurements up 90 GHz

25 November 2022 - Rohde & Schwarz, the only supplier of fast diode sensors for power measurements up to 67 GHz, is increasing the maximum measurable frequency of diode power sensors to 90 GHz; higher than any other diode sensor currently available. The diode technology enables 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 new R&S NRP90S and R&S NRP90SN power sensors combine an extraordinary 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, the 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.

Their portable form factor and flexible operating modes make all R&S NRPxxS power sensors ideal 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 analyzers, 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.

The new R&S NRP90S and R&S NRP90SN power sensors are now available from Rohde & Schwarz.
