Status and trends of silicon LDMOS base station PA technologies to go beyond 2.5 GHz applications

Abstract

LDMOS technology is the main power amplifier technology used for cellular base stations for frequencies up to 2.14 GHz. With the latest LDMOS technology generations it is however possible, and demonstrated, to use LDMOS for frequencies up to 3.8 GHz. This paper describes the status and trends of LDMOS technology for wireless applications beyond 2.5 GHz.go beyond 2.5 GHz applications.
