Procurement Notes

Verify the specific operating parameters against your circuit requirements, particularly the 4.7 V collector-emitter voltage limit and 20 mA current rating. Confirm that the TSLP-3 package dimensions align with your PCB layout constraints. Ensure compatibility with your intended RF frequency range up to 45 GHz. Check for any obsolescence notices or end-of-life status from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring high-frequency operation near 45 GHz with strict size limitations. Consider its silicon-germanium construction for superior noise figures compared to standard silicon devices. Evaluate the 4.7 V voltage rating to ensure it meets the power supply constraints of your application. The TSLP-3 package offers a balance between thermal performance and board space efficiency for dense layouts.
