RF Amplifiers Procurement Notes

Verify the specific package variant when ordering, as the A78 series includes both through-hole TO-8 and surface-mount options. Confirm that the required unit matches the SMA78 designation for the surface-mount configuration. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement specifications.

RF Amplifiers Selection Notes

Select this component for applications requiring wideband amplification between 2MHz and 350MHz with low noise characteristics. Consider the 15V supply requirement and TO-8 form factor during circuit design. Evaluate the need for hermetic sealing and MIL-STD-883 screening if the application involves harsh environmental conditions or high reliability standards.
