The 2-stage PAM is internally matched to 50 Ohms to minimize the use of external components and features a low-power mode to reduce standby current and DC power consumption during peak phone usage. High power-added efficiency and excellent linearity are achieved using Fairchild RF’s InGaP Heterojunction Bipolar Transistor (HBT) process.
