Procurement Notes

Verify the specific package variant required for the design, as the BLP9G0722-20 corresponds to the SOT1482-1 outline while the BLP9G0722-20G uses the SOT1483-1 outline. Confirm that the ordering suffix accurately reflects the intended lead configuration before finalizing procurement orders to ensure mechanical compatibility with the target PCB layout.

Selection Notes

Select this component for wideband base station power amplifier designs requiring robust performance across multiple cellular standards. Ensure the application circuit provides adequate heatsinking to maintain the junction temperature below the 225 °C maximum rating. Verify that the load impedance matches the provided typical impedance data for optimal power gain and drain efficiency at the target operating frequency.

Part Context

This part belongs to Ampleon's portfolio of plastic LDMOS power transistors specifically engineered for telecommunications infrastructure. It serves as a high-performance active element in RF power amplifier modules, enabling efficient signal amplification for various mobile network generations.
