Abstract :
The design, modeling, and characterization of an HBT cellular power amplifier using M/A-COM´s glass-based technology is presented. The power amplifier features a single positive supply with fully integrated on-chip input and on-chip output matching circuits. The amplifier exhibited greater than 62% PAE for a collector voltage from 3 to 6 V at 830 MHz operating frequency, which is a record-high PAE using an integrated matching network with a single positive supply.
