General description
A 1400 W extremely rugged LDMOS power transistor for broadcast and industrial
applications in the HF to 500 MHz band. This product is an enhanced version of the
BLF578 using Ampleon's XR process to provide maximum ruggedness capability in the
most severe applications without compromising the RF performance.
