Abstract
A tapered distributed power amplifier is designed for linear mobile phone power application, which covers the 3G mobile phone bandwidth from 800 MHz-2 GHz completely. It illustrates the opportunity of multiple power modes capability for power added efficiency (PAE) enhancement. Each power mode fulfills the WCDMA linearity specification up to a specific maximal output power.
