- Solution improves signal pointing accuracy by optimizing the
frequency, gain, and phase response of active antenna array
elements
- Automated and integrated test system reduces the arduous,
lengthy process of calibrating phased arrays from hours or days to
a few minutes
Keysight Technologies, Inc. (NYSE: KEYS) introduces the new
Phased Array Antenna Control and Calibration solution, a
breakthrough over-the-air (OTA) calibration and characterization
solution that enables satellite designers developing active
electronically scanned arrays for satellite communications
applications to rapidly test their designs during early
validation.
Modern satellite networks operate at higher frequencies and use
active phased array antenna systems which are driving ubiquitous
connectivity and sensing requirements of next-generation satellite
communication. Phased array antennas use electronic means to steer
beams to precise locations to improve overall reliability. Testing
these highly integrated systems is a complex and time-consuming
task. Designers and manufacturers need fast OTA testing to quickly
and efficiently calibrate and verify the performance of phased
arrays.
Keysight meets this need with a flexible measurement solution
that improves pointing accuracy and sidelobe rejection to reduce
interference effects on phased array antennas by optimizing the
frequency, gain, and phase response of active antenna array
elements.
The following are benefits of the Phased Array Antenna Control
and Calibration solution:
- Proprietary phased array calibration algorithms –
Enables highly-accurate measurement of gain and phase for a single
phased array element under test in an indirect far field test
environment. When combined with fast synchronization of radio
frequency (RF) test instruments, antenna positioning system, and
phased array control hardware, these algorithms reduce phased array
calibration times to minutes.
- Wide variety of verification tests – Includes fast gain
and phase calibration, effective isotropic radiated power (EIRP),
radiation pattern versus beam scan angle, beam scan and range loss,
cross-polarization isolation, gain compression, gain-over-noise
temperature (G/T), and modulation distortion (error vector
magnitude).
- Integrated solution – Features a single, user-friendly
software interface that controls the antenna under test, Keysight’s
high-performance test instruments, and Keysight’s compact antenna
test range positioner and temperature control unit.
- Maximizes existing test chambers – Retrofits into
existing anechoic chambers with the addition of a PNA-X vector
network analyzer and Phased Array Antenna Control and Calibration
solution.
The Phased Array Antenna Control and Calibration solution is a
part of the Keysight Antenna Measurement Toolset, which provides
engineers with a comprehensive set of antenna measurement tools,
including the option to provide a wide variety of non-signaling
antenna measurements such as frequency response, polar or full
spherical antenna patterns, and associated post-processing software
for 2D and 3D graphical representation.
Gregg Bell, General Manager of Aerospace and Defense RF
Products, Analog Devices, said: “Phased array is an enabling
technology in modern SatCom systems providing critical capability
over the parabolic dish. To overcome the potentially longer test
times and manufacturing complexity, Keysight offers this rapid test
and calibration solution. We are proud to work with a partner that
is continuously driving innovation and enabling significant
reduction in development and recurring costs for these phased array
antenna solutions.”
Greg Patschke, General Manager of Keysight’s Aerospace /
Defense and Government Solutions Group, said: “The rapid
adoption of phased array antenna technology in commercial and
military satellite communications is driving the need for automated
testing tools that can quickly and accurately calibrate systems for
mission success. The new Keysight Phased Array Antenna Control and
Calibration reduces the arduous and lengthy process of calibrating
complex, active phased array antennas from hours or days to just a
few minutes in a lab setting.”
