BLF981U

BLF981/BLF981S LDMOS Power Transistors

Ampleon BLF981/BLF981S Laterally Diffused Metal-Oxide-Semiconductor (LDMOS) Power Transistors are 170W devices designed for high-efficiency broadband applications across a wide frequency range from HF to 1400MHz. These transistors are particularly well-suited for use in broadcast transmitters, industrial, scientific, medical (ISM), avionics, and other non-cellular communication systems. Built to withstand extreme operating conditions, the Ampleon BLF981/BLF981S offers excellent ruggedness, high power gain, and integrated dual-sided ESD protection. The devices are optimized for both analog and digital signal transmission, ensuring reliable performance and easy power control. The BLF981 is housed in a SOT467C package, while the BLF981S comes in a SOT467B package, both supporting robust thermal management and long-term reliability.
