3.2. Antenna Connectors

The xE910 Mini PCIe adapter is equipped with a set of 50 Ω RF U.FL. connectors from
Hirose U.FL-R-SMT-1(10).

The available connectors are:

• Main RF antenna (ANT)

• RX Diversity Antenna (DIV)

• GNSS Antenna (GPS)

See the picture on the right for their position on
the interface.

The presence of all the connectors is depending
on the product characteristics and supported
functionalities.

4. Power Supply

The power supply circuitry and board layout are a very important part in the full product
design and they strongly reflect on the product overall performances, hence read the
requirements carefully and the guidelines that will follow for a proper design.

4.1. Power Supply Requirements

The external power supply must be connected to the pins 2, 39, 41, 52 and must fulfill
the following requirements:

POWER SUPPLY

Nominal Supply Voltage

3.3 V

Normal Operating Voltage Range

3.00 V÷ 3.60 V

NOTE:

The Operating Voltage Range MUST never be exceeded; care must be taken when
designing the application’s power supply section to avoid having an excessive voltage
drop.

If the voltage drop is exceeding the limits it could cause a Power Off of the module.

NOTE:

Overshoot voltage (regarding MAX Operating Voltage) and drop in voltage (regarding
MIN Operating Voltage) MUST never be exceeded;

4.2. Power Consumption

Please refer to the Module’s Hardware User guide for the details
The GSM system is made in a way that the RF transmission is not continuous, else it is

packed into bursts at a base frequency of about 216 Hz, and the relative current peaks
can be as high as about 2.4A. Therefore the power supply has to be designed in order
to withstand with these current peaks without big voltage drops; this means that both
the electrical design and the board layout must be designed for this current flow. If the
voltage drop during the peak current absorption is too much, then the device may even
shutdown as a consequence of the supply voltage drop.

NOTE:

The electrical design for the Power supply should be made ensuring it will be capable
of a peak current output of at least 2.4 A.

5.3. GSM/WCDMA/LTE/CDMA Antenna Requirements

The antenna connection is one of the most important aspect in the full product design
as it strongly affects the product overall performances, hence read carefully and follow
the requirements and the guidelines for a proper design.

The xE910 Mini PCIe adapter is provided with three RF connectors.
The available connectors are:

• Main RF antenna (ANT)

• RX Diversity Antenna (DIV)

• GNSS Antenna (GPS)

Connecting cables between the module and the antenna must have 50 Ω impedance.
If the impedance of the module is mismatched, RF performance is reduced
significantly.
If the host device is not designed to use the module’s diversity or GPS antenna,
terminate the interface with a 50Ω load.
