T&M solution
The R&S®ATS1000 antenna test system is a shielded
chamber solution ready to address the diverse antenna
testing market, especially highly integrated frontends of
phased array antennas. Each element of the phased array
antenna can also be characterized individually with the
R&S®AMS32 software. The R&S®ATS1000 fulfills all test-
ing requirements for 3D antenna pattern characterization
and antenna system characterization of AiP. The system
performs fast and reliable measurements in direct far-field
conditions in a fully anechoic chamber over the wide fre-
quency range from 18GHz to 87GHz.
To complement the R&S®ATS1000, a variety of state-of-
the-art Rohde & Schwarz test and measuring instruments
are avail able for testing AiP OTA parameters such as TRP,
EiRP and 3D patterns. One example is the R&S®ZNA, a
high-quality vector network analyzer (VNA) with high mea-
surement throughput, which accurately generates and
measures CW signals simultaneously.
In addition, the R&S®SMW200A vector signal generator
couples with the R&S®FSW signal and spectrum analyzer
to verify parameters such as ACLR, EVM and BER. The
R&S®ATS1000 accurately generates, measures and ana-
lyzes complex modulated signals and provides valuable
insights to further enhance the RF properties of AiP
modules.
Far-field scanner and 3D radiation patterns
AiP modules fit easily into the R&S®ATS1000 for direct far-
field OTA measurements. Moreover, the high-precision
conical cut positioner allows movements with extremely
high repeatability and an angular resolution of 0.03° for
both azimuth and elevation. Hardware triggering facili-
tates fast and accurate RF characterization of phased array
antennas.
Your task
AiP will give customers an advantage in the ever- changing
technological scene and pave the way for elegant 5G
antenna solutions and other millimeterwave applications.
Modules using AiP will miniaturize the antenna. These
modules will also have more antenna elements, which in-
creases radiation gain and enables more economical and
energy efficient solutions.
Challenges arise when chip manufacturers are confronted
with the key design constraints of phased array antennas.
Since RF components are fully integrated into the self-
contained module, conducted tests are no longer fea-
sible. Requirements for module optimization and valida-
tions all point to over-the-air (OTA) tests during system
level testing, integration and production. Millimeterwave
beamforming demands accurate, reliable and efficient
so lutions.
With its small footprint, the R&S®ATS1000 antenna test system is the ideal direct far-field OTA system to
test phased array antennas. The system tests and optimizes the radiation characteristics of any modules
using the AiP technology from 18GHz to 87GHz.
