Abstract

We report the performance of 0.18 μm RF power MOSFETs with an Asymmetric-Lightly-Doped-Drain(LDD) design. Such devices do not have an n-type drain extension and exhibited better characteristics than conventional MOSFETs at same gate length. The devices showed a DC breakdown voltage of 6.9 V, a 0.54 W/mm power density, 115 GHz fmax, and a good adjacent channel power ratio(ACPR) linearity, as well as a 52% drain efficiency at 2.4 GHz.
