This device has been transferred from Ampleon to Rochester Electronics.
HF/VHF power MOS transistor
Silicon N-channel enhancement mode vertical D-MOS transistor designed for large signal amplifier applications in the HF/VHF frequency range. The transistor has a 4-lead, SOT123A flange package, with a ceramic cap. All leads are isolated from the flange.
Features and benefits
- High power gain
- Low intermodulation distortion
- Easy power control
- Good thermal stability
- Withstands full load mismatch
- Gold metallization ensures excellent reliability
Applications
- Large signal amplifier applications in the HF/VHF frequency range
