Ampleon RF FETs, MOSFETs BLF981U

BLF981U is a 170 W LDMOS transistor in a flanged ceramic SOT467C package, designed for broadband RF applications up to 1400 MHz in broadcast, industrial, scientific, medical, and avionics systems. It features high efficiency (71% typ at 700 MHz), 24 dB power gain, and ruggedness capable of withstanding a VSWR of 40:1. The device includes integrated ESD protection, has a maximum drain-source voltage of 108 V, and operates with a junction temperature up to 225 °C. Thermal resistance from junction to case is 0.61 K/W. It is supplied in a tray of 60 pieces with non-dry pack. The part is RoHS compliant and meets ESD standards per ANSI/ESDA/JEDEC JS-001 (Class 2) and JS-002 (C2A).
