Description
Interface Schematic
1NC
Internal circuit node. Do not externally connect.
2VCC2 GSM
Controlled voltage input to the GSM driver stage. This voltage is part of
the power control function for the module. This node must be con-
nected to VCC OUT. This pin should be externally decoupled.
3NC
Internal circuit node. Do not externally connect.
4GND
Internally connected to the package base.
5GND
Internally connected to the package base.
6
GSM850/
GSM900
OUT
RF output for the GSM bands. This is a 50
Ω output. The output match-
ing circuit and DC-block are internal to the package.
7GND
Internally connected to the package base.
8NC
Internal circuit node. Do not externally connect.
9NC
Internal circuit node. Do not externally connect.
10
NC
Internal circuit node. Do not externally connect.
11
NC
Internal circuit node. Do not externally connect.
12
NC
Internal circuit node. Do not externally connect.
13
NC
No internal or external connection.
14
NC
Internal circuit node. Do not externally connect.
15
NC
Internal circuit node. Do not externally connect.
16
NC
Internal circuit node. Do not externally connect.
17
NC
Internal circuit node. Do not externally connect.
18
VCC3 GSM
Controlled voltage input to the GSM output stage. This voltage is part of
the power control function for the module. This node must be con-
nected to VCC OUT. This pin should be externally decoupled.
19
VCC OUT
Controlled voltage output to feed VCC2 and VCC3. This voltage is part
of the power control function for the module. It cannot be connected to
any pins other than VCC2 and VCC3.
20
VCC OUT
Controlled voltage output to feed VCC2 and VCC3. This voltage is part
of the power control function for the module. It cannot be connected to
any pins other than VCC2 and VCC3.
21
VCC3
DCS/PCS
Controlled voltage input to the DCS/PCS output stage. This voltage is
part of the power control function for the module. This node must be
connected to VCC OUT. This pin should be externally decoupled.
See pin 18.
