What is the PCB circuit design structure? With a host of questions in mind, we disassembled the Huawei RRU3908, an outdoor wireless base station with 20/40 watts of output power per RF front end.
Central Processing UnitsHuawei RRU3908 Receive PartHuawei RRU3908 Transmit PartHuawei RRU3908 Power AmplifierThe power amplifier uses two stages. Firstly a Infineon PTMA180402FL 40 Watt RF LDMOS. Secondly through a Xinger II XC1900A-03S hybrid coupler feeds two 90 degree out of phase signals to the output stage transistors which are NXP BLF6G20LS-140 140 Watt RF LDMOS. The output is recombined in a Xinger II XC1900A-03S hybrid coupler before leaving to th...See more on kaizerpowerelectronics.dkeeworld .cn
