LDMOS (Laterally Diffused Metal-Oxide-Semiconductor)

LDMOS (Laterally Diffused Metal-Oxide Semiconductor) is a type of power transistor used to control high currents and voltage in electronic devices. It operates by allowing electrical current to flow through a specially designed semiconductor region, with the current spreading laterally (side-to-side) across the device. This structure provides high efficiency, fast switching, and robustness, making it ideal for RF amplification and power applications such as radio transmitters and wireless communication equipment. In essence, LDMOS transistors efficiently switch and amplify large signals by leveraging carefully engineered semiconductor properties to handle power effectively.
