  • Patent number: 9502557
    Abstract: An LDMOSFET is designed with dual modes. At the high voltage mode, it supports a high breakdown voltage and is biased at a high voltage to get the benefits of high output power, higher output impedance and lower matching loss. At the low voltage mode, it exhibits a reduced knee voltage so that some extra voltage and power can be gained although it is biased at lower voltage. The efficiency is therefore improved as well.
