Specifications

Telit GE864 and GC864

Product Description

80273ST10008A Rev. 3 - 10/02/06

2.7.1 GC864 Antenna connector

The GC864 module is equipped with a 50 Ohm RF connector from Murata, GSC type P/N MM9329-

2700B.

The counterpart suitable is Murata MXTK92 Type or MXTK88 Type.

Moreover, the GC864 has the antenna pads on the back side of the PCB. This allows the manual

soldering of the coaxial cable directly on the back side of the PCB. However, the soldering is not

an advisable solution for a reliable connection of the antenna.

2.8 SIM card holder support (GC864 only)

The GC864 will have on the back side of the PCB, the necessary pads to manually solder a SIM

card holder. The type of the SIM card holder and its final position is being defined and will be

known soon.

2.9 Supply voltage

The external power supply must be connected to VBATT signal and must fulfill the following

requirements:

• Nominal operating voltage 3.8 V

• Operating voltage range 3.4 V - 4.2 V

Note

: Operating voltage range must never be exceeded; care must be taken in order to fulfill

min/max voltage requirements.

2.10 Power consumption

The typical current consumption of the Telit GE864 and GC864 are:

2.11 Embodied Battery charger

The battery charger is suited for 3.7V Li-Ion rechargeable battery (suggested capacity 500-

1000mAH). The Charger needs only a CURRENT LIMITED power source input and charges the

battery directly through VBATT connector pins.
