RF Diode Procurement Notes

Verify the exact ordering suffix against official Avago/Broadcom documentation to confirm lead-free status and packaging type. The datasheet indicates that adding 'G' to the end of the part number denotes a lead-free option. Confirm container details such as tape and reel dimensions or bulk quantities directly with authorized distributors to ensure compliance with specific manufacturing requirements.

RF Diode Selection Notes

Select this component for space-constrained wireless applications requiring low distortion diversity switching. Ensure the operating frequency falls within the 50MHz to 6GHz range. Verify bias conditions match the specified IF=10mA for optimal performance metrics like insertion loss and isolation. Consider the SOT-143 package size for board layout constraints.
