Pin No. 1 2 3 4 5 6 7 8 9 Pin Name Function Description Band Selection Tx Enable Selects the transmit band Starts the power A level high on this input selects the DCS chain. A zero selects the GSM chain. A level high on this pin enables the DCS/GSM chain and establishes a low–resistance link between pin 5 and 7 GSM–900 Biases the 900MHz section Biases the 1..
