Procurement Notes

Verify the specific datasheet revision, as MACOM reserves the right to change product information without notice. Confirm that the soft copper mounting flange has not been deformed during handling or transportation before installation. Ensure external gate protection components are included if required by the circuit design, as the device lacks internal monolithic zener diodes.

Selection Notes

Select this component for applications requiring high power output in the HF/VHF bands. Consider the thermal management requirements carefully, as the device relies on conduction cooling through the mounting flange. Account for the low impedance levels associated with high power outputs when designing matching networks. Verify that the operating frequency falls within the specified 2.0 to 100 MHz range for optimal performance.

Part Context

This device belongs to the MACOM RF Power MOSFET family, which includes various silicon-based transistors for radio frequency applications. These components are engineered for robust performance in demanding environments, often serving as key elements in transmitter chains where linearity and power handling are critical specifications.

Replacement Considerations

Consult official MACOM documentation for direct substitutes. Cross-referencing requires matching output power, frequency range, and package type. Verify thermal characteristics and pinout compatibility before implementation.
