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 />

Powerful GaN X-Band HPA<br />

Richardson RFPD, Inc., an Arrow<br />

Electronics company, announced the<br />

availability and full design support<br />

capabilities for a new gallium nitride<br />

high-power amplifier from United<br />

Monolithic Semiconductors. The<br />

CHA8312-99F is a two-stage GaN<br />

HPA that operates from 8 to 12 GHz<br />

and provides 17 W output power,<br />

50% power added efficiency, and<br />

26 dB small signal gain. The part<br />

is developed on a robust 0.15 µm<br />

gate length GaN on SiC HEMT process<br />
