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.

For more information about mating connectors, visit the website
http://www.hirose-connectors.com/

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.

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;

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.
