DESCRIPTION
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 1.8GHz section When pin 1 is at zero and pin 2 goes high, the LDO voltage appears on this pin (pin 14 is high) When pin 1 is at one and pin 2 goes high, the LDO voltage appears on this pin (pin 14 is high) When pin 2 goes high, the battery voltage appears on this pin with a 700m A peak current capability (pin 14 is high) The IC ground DCS- 1800 PA Start- up Gnd Enables the PA power section...
