The ARF463A is a discontinued RF power MOSFET from Advanced Power Technology (APT). It was designed for high-power, high-frequency applications, particularly in radio frequency amplifiers and transmitters.

Applications:

• RF power amplifiers
• HF and VHF transmitters
• Industrial heating equipment
• Medical RF applications
• MRI systems

Features:

• N-Channel Enhancement Mode
• High Power Capability
• High Gain
• Broadband Performance
• Low Output Capacitance

Benefits:

• Efficient amplification of RF signals
• High output power with minimal distortion
• Simplified circuit design due to high gain
• Wide frequency range coverage
• Improved performance in high-frequency applications

Additional Details:

The ARF463A is capable of delivering high power levels at frequencies up to several tens of MHz. It typically operates with a drain voltage of 125V and delivers power output on the order of hundreds of watts. It is typically packaged in a ceramic package for efficient heat dissipation and reliability at high frequencies. It's often chosen in high-power RF applications because of its performance characteristics. Due to its end-of-life status, finding a direct replacement may be necessary for new designs.
