LDMOS transistor basic information

The LDMOS (Laterally-Diffused Metal-Oxide-Semiconductor) transistor is a type of MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) with lateral field diffusion, which is widely used in RF and microwave applications due to its high power and efficiency. The MRFX1K80 transistor is one example of an LDMOS transistor used in high-frequency applications and features an …
