Procurement Notes

Verify part authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required variant, as ordering codes may indicate packaging or temperature ranges without altering core function. Request official datasheets and RoHS compliance certificates prior to purchase. Ensure supply chain integrity to avoid counterfeit components, especially given the component's status as obsolete or limited availability in some regions.

Selection Notes

Select this component when designing systems requiring high-gain vector multiplication within the 790MHz to 1.005GHz band. Consider the 32-TQFN package size for space-constrained PCB layouts. Evaluate the 15dBm input IP3 against system linearity requirements. Ensure compatibility with existing RF architectures supporting DCS, GSM, PCS, or UMTS protocols. Verify thermal management needs due to the exposed pad design.
