Abstract :
The advanced modulation formats used in 3G and 4G mobile systems have pushed the need for improved power amplifier linearity. The multi-function capability and sleeker form factor design of today´s smart phones have added more stringent requirements to the size and current consumption of power amplifier modules. This paper discusses some of the linear power amplifier module market trends and the technical challenges. It also presents several of TriQuint´s solutions, including the Tritium™ power amplifier and duplexer module (PAD) family, the Triton™ power amplifier module (PAM) family and WLAN front end modules (FEM) for handset.
