Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package details and compliance status. Confirm current product availability and lifecycle status directly with the manufacturer or authorized distributors, as component statuses may change over time. Ensure all handling precautions for electrostatic sensitive devices are strictly followed during procurement and storage.

Selection Notes

Select this component for broadband RF power amplifier designs operating between 2000 MHz and 2200 MHz. Ensure the application circuit supports a 28 V supply voltage and accommodates the required quiescent current. Verify that the host system provides adequate thermal management to maintain junction temperatures within the specified limits during high-power operation.

Part Context

This part belongs to the BLF6G22 series of power LDMOS transistors from Ampleon. The series is engineered for robust performance in wireless communication infrastructure.
