Vector Signal Transceiver to Cover X-Band Through Ka-Band<br />
Applications<br />
ted and calibrated switching for<br />
up to 32 channels. This enables<br />
multichannel beamformer and<br />
phased-array measurements<br />
without the need for additional<br />
infrastructure.<br />
The PXIe-5831 complements<br />
NI’s modular instrumentation<br />
portfolio of more than 600 PXI<br />
products, ranging from DC<br />
to mmWave. It also offers NI<br />
platform features such as highthroughput<br />
data movement using<br />
PCI Express Gen 3 bus interfaces<br />
and performs subnanosecond<br />
synchronization across PXI<br />
modules with integrated timing<br />
and triggering. Users can take<br />
advantage of the productivity<br />
of LabVIEW software, the flexibility<br />
of the LabVIEW FPGA<br />
Module and a vibrant ecosystem<br />
of partners, add-on IP and applications<br />
engineers. These benefits<br />
help them adapt to fast-changing<br />
technology and demanding technical<br />
requirements so they can<br />
deliver new systems on time and<br />
on budget. ◄<br />

NI vector signal transceivers<br />
help engineers reduce the cost<br />
and risk of design, validation<br />
and test for radar and Satcom<br />
devices with expanded frequency<br />
coverage up to 44 GHz.<br />
The PXIe-5831 vector signal<br />
transceiver (VST) addresses<br />
time-to-market challenges for<br />
X-band, Ku-band and Ka-band<br />
radar and satellite communications<br />
(Satcom) components and<br />
systems. The PXIe-5831 VST<br />
with modular millimeter wave<br />
(mmWave) heads expands the<br />
VST product family. It delivers<br />
1 GHz of instantaneous bandwidth<br />
for generation and analysis<br />
and features a high-performance<br />
FPGA, so users can perform<br />
faster and optimized measurements,<br />
inline signal processing<br />
and high-speed data transfer.<br />
The PXIe-5831 combines the<br />
PXIe-5820 baseband VST with<br />
the PXIe-3622 vector signal<br />
upconverter/downconverter for<br />
direct RF generation and analysis<br />
from 5 to 21 GHz. Modular<br />
mmWave heads further expand<br />
coverage to include frequencies<br />
from 23 to 44 GHz with integra-<br />
Tiny Embedded Antenna for Dualband WLAN<br />
Antenova, Ltd. has added a<br />
new, ultra-compact dualband<br />
Wi-Fi antenna to its range of<br />
tiny embedded antennas. The<br />
antenna, named Minuta, is a<br />
ceramic antenna measuring<br />
1 x 0.5 x 0.5 mm making it<br />
one of the smallest embedded<br />
antennas available today.<br />
Antenova has developed this<br />
antenna for the newer 4.9...5.9<br />
GHz frequency which is less<br />
cluttered than 2.4...2.5 GHz<br />
and gives enhanced performance<br />
with less interference.<br />
The Minuta antenna, part<br />
number SRC2W006, operates<br />
at 2.4...2.5 and 4.9...5.9<br />
GHz and matches the Wi-Fi<br />
802.11a/h/j/n/p/ac standards.<br />
It offers designers some useful<br />
flexibility in the layout of<br />
a PCB, as it does not need a<br />
position on a corner, it can be<br />
placed along one of the long<br />
edges of a board. The antenna<br />
is ideal for access points and<br />
portable devices, and in particular<br />
Antenova recommends<br />
Minuta for wearable technology<br />
and body-worn devices<br />
because it is less susceptible<br />
to de-tune when used close to<br />
the human body.<br />

Revolutionary Timing Technology solves<br />
Complex 5G Challenges<br />
RFMW, Ltd. announced<br />
design and sales support for a<br />
MEMS-based oven controlled<br />
oscillator (OCXO) platform.<br />
SiTime’s SiT5711 OCXO combines<br />
MEMS resonators with<br />
programmable analog, innovative<br />
packaging and highperformance<br />
algorithms for<br />
a vibration resistant solution<br />
that’s up to 20 times better<br />
than what’s currently available.<br />
The SiT5711 offers ±5<br />
ppb frequency stability and<br />
50 ppt/K frequency slope.<br />
Factory-programmed to any<br />
frequency between 1 and 60<br />
MHz, this OCXO is available<br />
in a 9 x 7 mm package making<br />
it the smallest OCXO available.<br />
It’s also available in common<br />
OCXO footprints such as 25<br />
x 22 mm, 20 x 13 mm, and<br />
14 x 9 mm to enable drop-in<br />
replacement of legacy quartz<br />
OCXOs. There are no restrictions<br />
on PCB placement and no<br />
mechanical shielding is needed<br />
for thermal isolation. Applications<br />
include 4G/5G remote<br />
radio heads (RRH) and pole top<br />
mounted radios, base stations,<br />
SONET/SDH Stratum 3E, core<br />
and edge routers, carrier class<br />
switches, IEEE 1588 grandmasters<br />
and instrumentation.<br />
