LDMOS (laterally-diffused metal-oxide semiconductor) [1] is a planar double-diffused MOSFET (metal–oxide–semiconductor field-effect transistor) used in amplifiers, including microwave power amplifiers, RF power amplifiers and audio power amplifiers.

This page explores the pros and cons of LDMOS (Laterally Diffused Metal Oxide Semiconductor) transistors. It highlights the benefits and drawbacks of LDMOS technology, along with a brief introduction to its structure.

A comparison of DMOS, VMOS, and LDMOS transistors, highlighting the structural and functional differences. Learn about the double diffusion, vertical structure, and lateral diffusion characteristics.

Sep 16, 2024 · An LDMOS (Laterally Diffused Metal Oxide Semiconductor) transistor is a type of Silicon based MOS transistor designed for high-power and high-frequency applications.

There are two major structural categories of RF MOSFETs in use today. These structures, DMOS (double-diffused Metal-Oxide-Semiconductor) and LDMOS (laterally diffused Metal-Oxide-Semiconductor), have unique behaviors: semiconductor process and geometry dependent.

LDMOS stands for lateral double-diffused MOSFET, the lateral version of power MOSFET, DMOS. Although some vendors offer RF versions of DMOS, its vertical structure has serious problems with excessive parasitic capacitance starting at around 500 MHz.

May 8, 2012 · We show the status of laterally diffused metal-oxide-semiconductor (LDMOS) technology, which has been the device of choice for RF power applications for more than one decade.

RF laterally diffused MOS (LDMOS) is currently the dominant device technology used in high-power RF power amplifier (PA) applications for frequencies ranging from 1 MHz to greater than 3.5 GHz.

In recent years lateral double-diffused MOS transistors (LDMOSFETs) have become the preferred devices for monolithic high-voltage and smart power applications. The advantages over VDMOSFETs are a reduction in the number of fabrication steps, multiple output capability on the same chip and compatibility with advanced VLSI technologies.
