Procurement Notes

Verify the component against official Infineon datasheets to confirm pinout compatibility and electrical specifications. Ensure that the ordering suffix matches the required tape and reel packaging format. Cross-reference the AEC-Q101 qualification status if automotive grade compliance is necessary for the specific design implementation.

Selection Notes

Select this component when designing circuits requiring dual low-noise amplification in a minimal footprint. Consider the 20 mA continuous drain current limit and 200 mW power dissipation constraints during thermal management planning. Verify that the operating frequency aligns with the specified power gain and noise figure characteristics at 45 MHz or 800 MHz.
