RF Mixers Procurement Notes

Verify the specific ordering suffix (TR, CT, DKR) required for your reel or cut tape needs against distributor availability. Confirm that the LGA-24 package dimensions align with your PCB footprint requirements. Ensure compliance with MSL level 3 handling procedures due to moisture sensitivity. Cross-reference the exact part number with official Analog Devices documentation to confirm current production status and RoHS compliance details before finalizing procurement orders.

RF Mixers Selection Notes

Select this component when a wideband double-balanced mixer is required for frequencies between 2.5 GHz and 7 GHz. Consider its 10.5 dB max conversion loss and 8.5 dB noise figure for system link budget calculations. The 24-pin LGA package necessitates careful thermal management given the 972 mW power dissipation rating. Evaluate the 18 dBm OIP3 specification against linearity requirements for your specific application environment.
