Pin Function Description
Interface Schematic
1
NC
Internal circuit node. Do not externally connect.
2
VCC2 GSM Controlled voltage input to the GSM driver stage. This voltage is part of
VCC2
the power control function for the module. This node must be con-
nected to VCC OUT. This pin should be externally decoupled.
3
NC
Internal circuit node. Do not externally connect.
4
GND
Internally connected to the package base.
5
GND
Internally connected to the package base.
6
GSM900 RF output for the GSM band. This is a 50Ω output. The output match-
OUT
ing circuit and DC-block are internal to the package.
VCC3
Output
Match
RF OUT
7
GND
Internally connected to the package base.
8
NC
Internal circuit node. Do not externally connect.
9
NC
Internal circuit node. Do not externally connect.
10
NC
Internal circuit node. Do not externally connect.
11
NC

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-
VCC3
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 Controlled voltage input to the DCS output stage. This voltage is part of See pin 18.
the power control function for the module. This node must be con-
nected to VCC OUT. This pin should be externally decoupled.
