Procurement Notes

Verify current availability status as distribution channels may indicate limited supply or special order requirements. Confirm that the specific suffix denotes the reel packaging format. Ensure compatibility with existing design specifications regarding voltage levels and interface protocols before finalizing procurement decisions.

Selection Notes

Select this component when a tunable band-pass filter is required for frequencies between 90 MHz and 225 MHz. Consider the 40-pin LGA package for space-constrained designs. Verify that the system can accommodate the necessary digital control interfaces and power supply rails specified in the datasheet.

Part Context

This part belongs to the ADMV8502 series of tunable band-pass filters manufactured by Analog Devices. It is designed for high-performance RF applications requiring adjustable frequency response.
