1 Introduction
1.1 Document Introduction
This document describes the electrical characteristics, RF performance, structure size, application
environment, etc. of NL652-EU-00 module. With the assistance of the document and other instructions,
the developers can quickly understand the hardware functions of the NL652-EU-00 module and develop
products.
1.2 Safety precautions
By following the safety guidelines below, you can protect the personal safety and help protect the product
and work environment from potential damage. Product manufacturers need to communicate the
following safety instructions to end users. In case of failure to comply with these safety rules, Fibocom
will not be responsible for the consequences caused by the user’s misuse.
Road safety first! When you drive, do not use the handheld devices even if it has a
hand-free feature. Please stop and call!
Please turn off the mobile device before boarding. The wireless feature of the mobile
device is not allowed on the aircraft to prevent interference with the aircraft
communication system. Ignoring this note may result in flight safety issue or even
breaking the law.
When in a hospital or health care facility, please be aware of restrictions on the use of
mobile devices. Radio frequency interference may cause medical equipment to
malfunction, so it may be necessary to turn off the mobile device.
The mobile device does not guarantee that an effective connection can be made under
any circumstances, for example, when there is no prepayment for the mobile device or
the (U)SIM is invalid. When you encounter the above situation in an emergency,
remember to use an emergency call, while keeping your device turned on and in areas
where signal is strong.
Your mobile device receives and transmits RF signals when it is powered on. Radio
interference occurs when it is near televisions, radios, computers, or other electronic
devices.

Keep the mobile device away from flammable gases. Turn off the mobile device when
near gas stations, oil depots, chemical plants or explosive workplaces. There is a
safety hazard in operating electronic equipment in any potentially explosive
environment.

The power stability can ensure the normal operation of NL652-EU-00 series module. Special attention
requires when design circuit that the power supply ripple limit for the module is no more than 150mV (the
circuit ESR < 100mΩ). When the module is operating in GSM mode (Burst transmit), the maximum
operating current can reach 3A, and the power voltage needs to be at least 3.15V. Otherwise, the module
may power off or restart. The power limit is shown in Figure 4-2:
