Overview
The BLF177R, produced by Ampleon USA Inc., is a high-performance HF/VHF power MOS transistor. This silicon N-channel enhancement mode vertical D-MOS transistor is encapsulated in a 4-lead, SOT121B flanged package with a ceramic cap. All leads are isolated from the flange, ensuring robust and reliable operation. The device is designed to provide high power gain, low intermodulation distortion, and good thermal stability, making it suitable for demanding applications in the HF/VHF frequency range.
