Enhancement on the robustness of a quad-band power amplifier module for GSM/GPRS handsets

Device ruggedness is the major concern about the adoption of power amplifier module in the mobile phone industry. A resistive network was employed to stabilize the sub-harmonic (f/2) loop oscillation for the large periphery device, especially on the output stage. Not only the spurious emission being...
