N-Channel RF Amplifier
Features
• This device is designed for VHF/UHF amplifier, oscillator and mixer applications.
• As a common gate amplifier, 16 dB at 100 MHz and 12 dB at 450 MHz can be realized.
• Sourced from Process 92.
• Source & Drain are interchangeable.
Absolute Maximum Ratings *
* These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
NOTES:
1) These ratings are based on a maximum junction temperature of 150 degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle
Thermal Characteristics
* Device mounted on FR-4 PCB 1.6" X 1.6" X 0.06".
