Procurement Notes

Verify component authenticity through authorized Ampleon distributors or official channels. Confirm RoHS compliance status as specified in the product data sheet. Ensure proper ESD handling protocols are followed during transport and assembly due to integrated protection sensitivity. Validate package type SOT502B earless flanged ceramic packaging matches design requirements before procurement.

Selection Notes

Select this component for broadband RF power amplifier designs operating between 1800 MHz and 2000 MHz. Ensure thermal management supports the 0.49 K/W junction-to-case resistance under class-AB operation conditions. Verify that system voltage limits do not exceed the 65 V drain-source breakdown rating. Consider internal matching network integration when designing input and output circuits for optimal performance.

Part Context

This part belongs to the Ampleon LDMOS power transistor family optimized for cellular infrastructure. It utilizes laterally diffused metal oxide semiconductor technology to deliver high linearity and efficiency. The device is specifically engineered for multi-carrier base station environments requiring robust performance across wide bandwidths without external matching components.

Replacement Considerations

Consult official Ampleon documentation for verified substitute part numbers. Cross-reference electrical parameters including power output, frequency range, and package dimensions before substitution.
