Cellular Module Featuring an Embedded SIM<br />
u-blox has announced the u-blox<br />
SARA-R500E, its first cellular<br />
module with an embedded SIM<br />
chip (eSIM). Offering LTE-M<br />
connectivity, SARA-R500E is<br />
designed for size-constrained<br />
applications with high requirements<br />
in terms of robustness<br />
and security, such as connected<br />
healthcare and asset trackers.<br />
The first variant of the module<br />
will offer out-of-the-box connectivity<br />
on a North American<br />
LTE-M cellular network.<br />
eSIMs are increasingly gaining a<br />
foothold in devices offering cellular<br />
connectivity. Today, most<br />
such devices, including the vast<br />
majority of smartphones, still<br />
feature a plastic SIM card that<br />
contains all the attributes and<br />
features required to connect the<br />
device to the cellular network.<br />
Like the plastic SIMs they are<br />
designed to replace, eSIMs are<br />
provisioned with a profile that<br />
allows devices to connect to a<br />
specific mobile network operator.<br />
Robust, secure, and compact:<br />
The eSIM embedded in the<br />
SARA-R500E offers product<br />
developers and end-users important<br />
advantages. eSIMs are more<br />
robust than standard plastic SIMs<br />
and cannot be stolen or removed,<br />
increasing the security of the<br />
device. By doing away with the<br />
components required to hold and<br />
connect plastic SIM cards, they<br />
enable smaller devices, reduce<br />
the bill of material and simplify<br />
manufacturing. Finally, SARA-<br />
R500E streamlines sourcing by<br />
offering the module, data plans,<br />
and the SIM from one house.<br />
The fact that the SARA-R500E<br />
module’s eSIM does not need to<br />
be inserted manually by the enduser<br />
allows product developers<br />
to design tightly sealed devices<br />
that meet the demanding IP67<br />
and IP68 criteria. This makes<br />
the module ideal for rugged<br />
IoT applications such as smart<br />
meters, surveillance cameras,<br />
and environmental sensors.<br />
The module also offers the option<br />
to access u-blox’s MQTT Anywhere<br />
service, which reduces<br />
bandwidth requirements for cellular<br />
data transfer, saving costs<br />
and power. u-blox IoT Locationas-a-service<br />
portfolio, including<br />
AssistNow for real-time GNSS<br />
assistance data, and CellLocate,<br />
for cellular network-based positioning,<br />
is also available. SARA-<br />
R500E is pin-to-pin compatible<br />
with all the other modules in<br />
the SARA family and uses the<br />
SARA-R5 AT command interface,<br />
making it easy to drop<br />
the SARA-R500E into existing<br />
designs.<br />

5G, Low-PIM, In-Building DAS<br />
Antennas<br />
KP Performance Antennas, an<br />
Infinite Electronics brand and<br />
a manufacturer of wireless network<br />
antennas, has just introduced<br />
a new series of 5G, low-<br />
PIM, in-building DAS antennas<br />
covering 600 MHz to 6 GHz. The<br />
indoor wall-mount and ceiling<br />
mount antennas meet the demand<br />
that in-building wireless distributed<br />
networks have for highquality<br />
antennas with low-PIM<br />
ratings, SISO and MIMO support<br />
and wide bandwidth coverage.<br />
These new 5G, low-PIM antennas<br />
are 700 MHz FirstNet/First<br />
Responder Network ready and<br />
suitable for indoor DAS, private<br />
networks, hospital and enterprise<br />
deployments. They also feature<br />
Type N and 4.3-10 connector<br />
options for improved PIM consistency<br />
as well as a low passive<br />
intermodulation of less than<br />
minus-150 dBc when tested with<br />
2 x 20 W tones.<br />

300-W Fixed Attenuator<br />
BroadWave Technologies<br />
announced a 300-W fixed attenuator<br />
series, designed for wireless<br />
applications. These attenuators<br />
reduce the amount of power<br />
delivered in a transmission line<br />
without introducing much noise<br />
or distortion. Model series 352-<br />
023-XXX is a 50-ohm fixed<br />
attenuator with an operating frequency<br />
range of DC to 2.4 GHz.<br />
Standard attenuation values are<br />
3, 6, 10, 20, and 30 dB. Maximum<br />
SWR is 1.25, the temperature<br />
range is - 40 to +40 °C and<br />
the RF connectors are N male/N<br />
female. Other RF connector<br />
types and genders are available<br />
in this package. Additional applications<br />
include test equipment,<br />
telecommunication systems,<br />
base stations, radar applications<br />
and defense programs.<br />
