Abstract
A radio frequency (RF) system is described for use in a wireless communication device. The RF system may contain power amplifiers, additional circuitry and components (e.g., gain controllers, phase shifters), and/or antennas. The RF system is described in a variety of different configurations with its functionality divided up over several single chip circuits. Using the single chip circuits simplifies assembly, reduces size, and allows for high speed RF performance demanded by fixed and mobile wireless standards. The system may use a first amplifier circuit combined with an adjacent channel leakage correction circuit so that the output of the first amplifier has the signal leakage substantially cancelled.
