R&S NRP90S and NRP90SN diode power sensors

Rohde & Schwarz is increasing the maximum measurable frequency of its diode power sensors to 90 GHz. The diode technology enables fast power measurements with high sensitivity from a compact and lightweight 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 R&S NRP90S and R&S NRP90SN power sensors combine a frequency range of 50 MHz to 90 GHz with a dynamic range from –70 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 is said to increase the power measurement dynamic range by 35 dB and to cut test times.

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

Their portable form factor and flexible operating modes make the power sensors suitable for both local and remote installation in maintenance or monitoring applications, with users benefiting from high 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 NRP90SN also includes an Ethernet interface to support remote LAN operation.
