RF Switches Procurement Notes

Verify the specific ordering suffix TE1 to ensure compatibility with tape-and-reel packaging standards. Confirm that the 18-EQFN footprint matches the target PCB layout dimensions. Check RoHS3 compliance status if required by environmental regulations. Ensure the supply voltage range aligns with the system's logic levels for proper control interface operation.

RF Switches Selection Notes

Select this component when a SP4T configuration is required for frequencies up to 6 GHz. Prioritize this part for designs needing high linearity (60 dBm IIP3) and low insertion loss (0.5 dB). Consider the 1.8 V minimum control voltage for compatibility with low-power logic interfaces. Evaluate the 18-EQFN package size against available board space constraints.
