RF Mixers Procurement Notes

Verify the specific suffix (+ or +T) against your manufacturing requirements, as packaging differs between tube and reel formats. Confirm current availability status directly with authorized distributors, as supply constraints may apply. Ensure the TQFN-EP-36 footprint matches your PCB layout specifications before finalizing orders.

RF Mixers Selection Notes

Select this component when high linearity and low noise are critical for downconversion tasks in the 700MHz to 1GHz band. The integrated LO buffer reduces external component count compared to discrete mixer solutions. Evaluate thermal dissipation capabilities, as the device handles significant power consumption within its compact package form factor.
