| Pin | Function | Description | Interface Schematic |
| 31 | DCS/PCS OUT | RF output for the DCS/PCS bands. This is a 50Q output. The output matching circuit and DC-block are internal to the package. | See pin 6 |
| 32 | GND | Internally connected to the package base. | |
| 33 | NC | Internal circuit node. Do not externally connect. | |
| 34 | GND | Internally connected to the package base. | |
| 35 | VCC2 DCS/PCS | Controlled voltage input to the DCS/PCS driver 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 2 |
| 36 | NC | No internal connection. Connect to ground plane close to the package pin. | |
| 37 | DCS/PCS IN | RF input to the DCS/PCS band. This is a 50Q output. | VCC1 ~ |
| 38 | NC | No internal connection. Connect to ground plane close to the package pin. | |
| 39 | VCC1 DCS/PCS | Controlled voltage on the GSM and DCS/PCS preamplifier stages. This voltage is applied internal to the package. This pin should be externally decoupled. | VCC1 |
| 40 | BAND SEL | Allows external control to select the GSM or DCS/PCS bands with a logic high or low. A logic low enables the GSM bands, whereas a logic high enables the DCS/PCS bands. | BAND SEL >GSM CTRL TX EN >DCS CTRL |
| 41 | TX ENABLE | This signal enables the PA module for operation with a logic high. Both bands are disabled with a logic low. | VBATT TX EN TX ON |
| 42 | VBATT | Power supply for the module. This pin should be externally decoupled and connected to the battery. | |
| 43 | VBATT | Power supply for the module. This pin should be externally decoupled and connected to the battery. | |
| 44 | NC | Internal circuit node. Do not externally connect. | |
| 45 | VRAMP | Ramping signal from DAC. A simple RC filter may be required depend- ing on the selected baseband. | VRAMP.~~V::11> |
| 46 | VCCl GSM | Internally connected to VCCl (pin 39). No external connection required. | See pin 39. |
| 47 | GNDl GSM | Ground connection for the GSM preamplifier stage. Connect to ground plane close to the package pin. | |
| 48 | GSM850/ GSM900 IN | RF input to the GSM band. This is a 50Q input. | See pin 37. |
| Pkg Base | GND | Connect to ground plane with multiple via holes. See recommended footprint. | |
