1

DCS/PCS_IN

RF input to the DCS/PCS PA. There is a 175  shunt resistor before the DC

blocking capacitor to set the input impedance

2

BS

Band select logic pin. Logic low selects the GSM PA and a logic high selects

the DCS/PCS PA

3

TX_EN

TX enable logic pin, a logic high will enable the PA

4

VBATT

Battery supply connection

5

VMODE

Logic pin for selection of GMSK or 8PSK (EDGE) mode. A logic low selects

GMSK mode and a logic high selects the 8PSK mode

6

VRAMP

Analog output power control pin

7 GSM850/900_IN RF input to GSM850/900 PA.

VBIAS logic input. A logic low sets a low bias point for current savings at low

8

VBIAS

power levels, a logic high sets a high bias point for meeting linearity

perfomance up to the maximum specified linear ouptut power
