RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix 'ETR' matches your reel requirements. Request current lifecycle status documentation to ensure long-term availability for production designs. Validate RoHS compliance data against the latest datasheet revision before finalizing procurement orders.

RF Mixers Selection Notes

Select this component when designing low-noise down-conversion stages for 1.4–2.3 GHz signals. The integrated LO amplifier simplifies circuit topology by reducing external component count. Ensure the system can accommodate the 11 dB noise figure impact on overall receiver sensitivity. Verify that the 16-SSOP package dimensions fit the target PCB layout constraints.
