NOVEL LDMOS STRUCTURE FOR 2 GHz HIGH POWER BASESTA TION APPLICATION H.F.F. Jos Philips Semiconductors DSC-N, Gerstweg 2,6534 AE Nijmegen. The Netherlands Rik.Jos-nym.sc.philips.com ABSTRACT An LDMOS is described for high power (>70W) 2 GHz basestation application that includes several novel structures. High power gain is achieved by minimizing gate resistance and feedback capacitance. The gate
