Hardware Integration Guide
RF Connections
When attaching antennas to the module:
(cid:129)
Use Hirose U.FL connectors (3 mm x 3 mm, low profile; model
U.FL #CL331-0471-0-10) to attach antennas to connection points on the module.
Note: To disconnect the antenna, make sure you use the Hirose U.FL connector removal tool
(P/N UFL-LP-N-2(01)) to prevent damage to the module or coaxial cable assembly.
(cid:129) Match coaxial connections between the module and the antenna to 50 .
(cid:129) Minimize RF cable losses to the antenna; the recommended maximum cable loss for
(cid:129)
antenna cabling is 0.5 dB.
To ensure best thermal performance, mounting holes must be used to attach (ground)
the device to the main PCB ground or a metal chassis.
Note: If the antenna connection is shorted or open, the modem will not sustain permanent damage.
The module is fully shielded to protect against EMI and the shield must not be removed.
Shielding
Antenna and Cabling
When selecting the antenna and cable, it is critical to RF performance to match antenna
gain and cable loss.
Choosing the Correct Antenna and Cabling
When matching antennas and cabling:
The antenna (and associated circuitry) should have a nominal impedance of 50
with a recommended return loss of better than 10 dB across each frequency band of
operation.
The system gain value affects both radiated power and regulatory (FCC, IC, CE, etc.)
test results.
Designing Custom Antennas
Consider the following points when designing custom antennas:
A skilled RF engineer should do the development to ensure that the RF performance
is maintained.
If both UMTS and CDMA modules will be installed in the same platform, you may
want to develop separate antennas for maximum performance.
Determining the Antenna’s Location
When deciding where to put the antennas:
Antenna location may affect RF performance. Although the module is shielded to
prevent interference in most applications, the placement of the antenna is still very

(cid:129)
(cid:129)
important—if the host device is insufficiently shielded, high levels of broadband or
spurious noise can degrade the module’s performance.
Connecting cables between the module and the antenna must have 50 impedance.
If the impedance of the module is mismatched, RF performance is reduced signifi-
cantly.
Antenna cables should be routed, if possible, away from noise sources (switching
power supplies, LCD assemblies, etc.). If the cables are near the noise sources, the
noise may be coupled into the RF cable and into the antenna.
Disabling the Diversity Antenna
Certification testing of a device with an integrated MC7411 may require the module’s main
and diversity antennas to be tested separately.
To facilitate this testing, receive diversity can be enabled/disabled using AT commands:
!RXDEN—Used to enable/disable diversity for single-cell call (no carrier aggre-
(cid:129)
gation).
!LTERXCONTROL—Used to enable/disable paths (in carrier aggregation scenarios)
after a call is set up.
(cid:129)
Important: LTE networks expect modules to have more than one antenna enabled for proper
operation. Therefore, customers must not commercially deploy their systems with the diversity
antenna disabled.
Note: A diversity antenna is used to improve connection quality and reliability through redundancy.
Because two antennas may experience difference interference effects (signal distortion, delay, etc.),
when one antenna receives a degraded signal, the other may not be similarly affected.
Ground Connection
When connecting the module to system ground:
Prevent noise leakage by establishing a very good ground connection to the module
through the host connector.
Connect to system ground using the two mounting holes at the top of the module.
(cid:129) Minimize ground noise leakage into the RF.
Depending on the host board design, noise could potentially be coupled to the
module from the host board. This is mainly an issue for host designs that have signals
traveling along the length of the module, or circuitry operating at both ends of the
module interconnects.
Interference and Sensitivity
Several interference sources can affect the module’s RF performance (RF desense).
Common sources include power supply noise and device-generated RF.
RF desense can be addressed through a combination of mitigation techniques (Methods
to Mitigate Decreased Rx Performance on page 12) and radiated sensitivity measurement
(Radiated Sensitivity Measurement on page 13).
Rev. 2 January 2021

Hardware Integration Guide
Note: The MC7411 is based on ZIF (Zero Intermediate Frequency) technologies. When performing
EMC (Electromagnetic Compatibility) tests, there are no IF (Intermediate Frequency) components
from the module to consider.
Interference From Other Wireless Devices
Wireless devices operating inside the host device can cause interference that affects the
module.
To determine the most suitable locations for antennas on your host device, evaluate each
wireless device’s radio system, considering the following:
Any harmonics, sub-harmonics, or cross-products of signals generated by wireless
devices that fall in the module’s Rx range may cause spurious response, resulting in
decreased Rx performance.
The Tx power and corresponding broadband noise of other wireless devices may
overload or increase the noise floor of the module’s receiver, resulting in Rx desense.
The severity of this interference depends on the closeness of the other antennas to the
module’s antenna. To determine suitable locations for each wireless device’s antenna,
thoroughly evaluate your host device’s design.
Host-generated RF Interference
All electronic computing devices generate RF interference that can negatively affect the
receive sensitivity of the module.
Proximity of host electronics to the antenna in wireless devices can contribute to
decreased Rx performance. Components that are most likely to cause this include:
(cid:129) Microprocessor and memory
Display panel and display drivers
Switching-mode power supplies
Device-generated RF Interference
The module can cause interference with other devices. Wireless devices such as AirPrime
embedded modules transmit in bursts (pulse transients) for set durations (RF burst
frequencies). Hearing aids and speakers convert these burst frequencies into audible
frequencies, resulting in audible noise.
Methods to Mitigate Decreased Rx Performance
It is important to investigate sources of localized interference early in the design cycle. To
reduce the effect of device-generated RF on Rx performance:
Put the antenna as far as possible from sources of interference. The drawback is that
the module may be less convenient to use.
Shield the host device. The module itself is well shielded to avoid external inter-
ference. However, the antenna cannot be shielded for obvious reasons. In most

instances, it is necessary to employ shielding on the components of the host device
(such as the main processor and parallel bus) that have the highest RF emissions.
Filter out unwanted high-order harmonic energy by using discrete filtering on low
frequency lines.
Form shielding layers around high-speed clock traces by using multi-layer PCBs.
Route antenna cables away from noise sources.
(cid:129)
(cid:129)
(cid:129)
Radiated Spurious Emissions (RSE)
When designing an antenna for use with AirPrime embedded modules, the host device
with an AirPrime embedded module must satisfy any applicable standards/local
regulatory bodies for radiated spurious emission (RSE) for receive-only mode and for
transmit mode (transmitter is operating).
Note that antenna impedance affects radiated emissions, which must be compared
against the conducted 50-ohm emissions baseline. (AirPrime embedded modules meet
the 50-ohm conducted emissions requirement.)
Radiated Sensitivity Measurement
A wireless host device contains many noise sources that contribute to a reduction in Rx
performance.
To determine the extent of any receiver performance desensitization due to self-generated
noise in the host device, over-the-air (OTA) or radiated testing is required. This testing can
be performed by Sierra Wireless or you can use your own OTA test chamber for in-house
testing.
