power amplifiers and audio power amplifiers . these transistors are often fabricated on p/p+ silicon epitaxial layers. the fabrication of ldmos devices mostly involves various ion-implantation and subsequent annealing cycles. [ ] as an example, the drift region of this power mosfet is fabricated using

voice and data traffic . [ ] ldmos devices are widely used in rf power amplifiers for base-stations as the requirement is for high output power with a corresponding drain to source breakdown voltage usually above volts . [ ] compared to other devices such as gaas fets they show a lower maximum power...
