Hi everyone. My name is Adeline Lim and I am an engineer at the Electronic Measurement Group of Agilent Technologies, soon to become Keysight Technologies.
We are here to fulfill all our customer needs and when we hear that there is a growing interest in E-band spectrum,
we knew we had to come out with a solution.
Today, I am here to talk about the new E8486A E-band waveguide power sensor
that can be used in several applications such as wireless mobile backhaul, automotive radar, and mm-wave research.
The new E-band power sensor covers the frequency range of 60 to 90 GHz, and comes with two options:
the standard option, covering -30 to +20 dBm, and a wider dynamic range option, covering -60 to +20 dBm.
This wide dynamic range option comes with EEPROM to store calibration factors, which will shorten your setup time.
Now let’s talk about the first application which is the mobile backhaul transceiver power measurement.
With the increasing demand for ultra-high data rates for LTE Advanced and other emerging wireless technologies,
mobile backhaul has moved into the E-band spectrum in the recent years.
The point-to-point (P2P) communication link in E-band handles the high data capacity requirement and has fewer licensing restrictions.
The E8486A comes with a WR-12 connector that is used in most wireless backhaul systems,
so you don’t need purchase a separate connector.
The WR-12 waveguide connection allows precise measurement with near-perfect matching
between the transmitter out of the test port and the power sensor.
The wide dynamic range option, which measures down to -60 dBm,
also allows you to measure lower level signals while maintaining high measurement accuracy.
The E8486A comes with the best SWR performance of 1.06, allowing you to further minimize mismatch measurement uncertainty.
Automotive radar has also shifted toward the E-band spectrum, with more applications operating in the 76 to 81 GHz range.
Radars operating in the E-band spectrum are designed to support various objectives such as
adaptive cruise control, blind spot detection, and many other road safety features.
A simple test configuration can be setup using two E8486A waveguide power sensors.
Last but not least, the waveguide sensor is popular among mm-wave researchers and education sectors.
Waveguide power sensors are commonly used for high-power mm-wave applications
because they provide better transmission with low loss and good shielding.
When measuring the RF power using power meters and sensors,
the connectors on the power sensors must be selected correctly in order to reduce mismatch measurement uncertainty.
For example, the E8486A can be used for E-band RF power calibration and leveling,
which is traceable to standards set by the National Institute of Standard and Technology (NIST).
As you have heard, the E-band waveguide power sensor provides very accurate power measurements in 60 to 90 GHz frequency range.
We also have the V-band and W-band sensor to meet your application needs.
