Patent ID: 8416545

Claim:
A power amplifier module, comprising: a power amplifier (PA) controller including an input conductive pad receiving power, a low drop output (LDO) part receiving power from the input conductive pad to supply operating power, an electrostatic discharge (ESD) protection circuit connected to an output terminal of the LDO part, an output conductive wire pad outputting the operating power of the LDO part; a printed conductive wire pad electrically connected to the output conductive wire pad of the PA controller; a first power coupler including a first primary side conductive wire electrically connected to the printer conductive wire pad; a second power coupler including a second primary side conductive wire electrically connected to the printed conductive wire pad; a first PA part connected to both ends of the first primary side conductive wire to receive operating power and amplify a signal including a predetermined first band and to output the amplified signal to the first power coupler; and a second PA part connected to both ends of the second primary side conductive wire to receive the operating power and amplify a signal including a predetermined second band and output the amplified signal to the second power coupler, the first PA part and the second PA part each being protected from ESD by the ESD protection circuit.
