Applications

• JTIDS transmitters
• Mode-S transmitters
• Long pulse common base amplifiers
• Short pulse common base amplifiers

Procurement Notes

Verify the specific datasheet revision (e.g., Rev. V1) against the manufacturer's official documentation before procurement. Confirm that the application environment supports the required 36Vdc operating conditions and that the hermetic package style aligns with the system's thermal and mechanical constraints.

Selection Notes

Select this component for designs requiring high peak output power in the L-band spectrum. Ensure the circuit topology utilizes a common base configuration to leverage the internal input matching. Verify that the load impedance matches the series equivalent values provided in the datasheet to achieve the specified gain and efficiency metrics.

Part Context

This part belongs to MACOM's line of microwave power silicon NPN transistors. It is specifically engineered for robust performance in military and aerospace communication systems where reliability under high VSWR conditions is critical. The device utilizes silicon nitride passivation and gold metallization to ensure longevity.

Replacement Considerations

Consult the official MACOM replacement guide for direct equivalents. Cross-referencing requires matching the frequency range, peak power output, and package type to ensure functional compatibility without redesigning the surrounding RF circuitry.
