Procurement Notes

Verify the end-of-life status before design finalization, as this component is marked as obsolete. Confirm availability through authorized distributors or secondary market channels. Ensure that any replacement strategy accounts for the discontinuation timeline. Validate that the M252 package footprint remains compatible with existing board layouts if retrofitting is considered.

Selection Notes

Select this component only when specific RF parameters such as 120 W output power and 14 dB gain are required. The 65 V breakdown voltage suits moderate voltage RF environments. Consider the M252 package constraints during PCB layout. Evaluate thermal requirements given the 236 W dissipation rating. Verify compatibility with 1 GHz operating frequencies for the target application.
