Instructions for Use:

1. Power Supply Connection: Connect the power supply terminals to a regulated power source within the specified range of +12V to +14V DC. Ensure proper polarity.
2. RF Input and Output Connections: Connect the RF input and output to 50 Ω impedance matching networks or directly to your transmission line. Ensure that all connections are secure and properly shielded to prevent interference.
3. Heat Dissipation: The LA4460N is designed to dissipate heat efficiently through its TO-220F package. However, it may require a heatsink depending on the operating conditions and duty cycle.
4. Biasing: The amplifier is internally biased, so no external biasing components are required for operation under normal conditions.
5. Testing: Before full-power testing, verify all connections and perform initial tests at reduced power levels to ensure correct operation and avoid potential damage.
6. Handling Precautions: Handle with care to avoid static discharge, which can damage sensitive components. Use appropriate ESD protection measures.
