24-GHz band to 79-GHz. "The 4-GHz instantaneous bandwidth greatly improves
the range resolution, accuracy, and reliability of object detection, and the higher
frequency reduces the device size. The
R&S ATS1500C over-the-air antenna test
chamber has been designed to meet requirements for 79-GHz automotive radar
test, for R&D, validation, and calibration,
in combination with the R&S AREG."
The R&S ATS1500C features a CATR reflector, providing a 30-cm diameter quiet
zone-large enough to test the largest automotive radar sensor aperture used for
the frequency band, Lörner said, while the
R&S AREG100A automotive radar echo
generator can include interference while
generating up to four echoes simultaneously, all with the in-demand 4-GHz
maximum instantaneous bandwidth.

of next-generation mmWave communications, satellite communications, and
radar applications," Keysight said.

Characterization to production
Rohde & Schwarz is addressing various
aspects of RF/microwave test, including
characterization, network rollout, automotive radar, and cross-channel measurements, according to Markus Lörner,
market segment manager industry components, research and universities.
For network rollout, Lörner said, 5G operators can employ the R&S TSME30DC
drive-test scanner. "Networks anchored
in LTE, or making use of dynamic shared
spectrum (DSS) to transmit 5G-related
data using part of the LTE spectrum, or
with separate networks utilizing FR1 and
FR2 frequencies, can scan both frequency
ranges simultaneously to save time and
effort, by using the R&S TSME30DC with
a suitable drive-test scanner," he said,
adding that frequencies from 450 MHz
to 6 GHz and 24 to 30 GHz can be scanned
simultaneously.
Lörner pointed out that automotiveradar applications are migrating from the

Rohde & Schwarz ATS1500C over-the-air
antenna test chamber.

According to Adam Smith, director
of product marketing at LitePoint, the
company's product focus for 2020 is in
three main areas: 5G, both sub-6-GHz
FR1 and mmWave FR2; Wi-Fi 6E, utilizing

the 6-GHz unlicensed band; and UltraWideband (UWB), based on an emerging
application space in accurate positioning
and ranging.
"LitePoint has recently released new
products to address the unique technical requirements of each of the technologies listed above," Smith said. First, he
described the IQgig-5G Model B as "Our
second-generation 5G mmWave product
focused on scaling 5G mmWave FR2 endproducts to high-volume manufacturing. Currently, the IQgig-5G is the only
fully-integrated mmWave test system in
the market, deployed on manufacturing
lines testing up to four devices in parallel.
Further, IQgig-5G offers best-in-class error vector magnitude (EVM) performance
across all existing and forthcoming 3GPP
bands, in a contiguous 23- to 45-GHz
range."
Smith said the IQxel-MW 7G is specifically targeted at testing Wi-Fi
6E products. "The IQxel-MW 7G is a
fully-integrated wireless connectivity test solution that addresses the
high-performance needs of products
launching later this year, operating in
the new 6-GHz unlicensed band (6 to
7.125 GHz)," he said. "IQxel-MW 7G is
a reference solution at silicon solution
providers, backward-compatible with
LitePoint's widely-deployed installed
base of IQxel family testers, enabling
companies integrating the latest Wi-Fi
technology to get to market (and volume)
quickly."
Smith also commented on the IQgigUWB. "UWB technology introduces
some very unique requirements that
do not conform to traditional wireless
connectivity standards like Wi-Fi or
Bluetooth," he said. "Specifically, UWB
operates in a frequency range up to 10.6
GHz at instantaneous signal bandwidths
of approximately 500 MHz to more than
