• Wireless communication systems

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific LP3E suffix indicates the leadless surface mount package variant. Ensure compliance with relevant RoHS directives and check for any end-of-life notices or limited availability status prior to finalizing procurement plans.

Selection Notes

Select this component when a low-noise, programmable divider is required for frequencies up to 2 GHz. The SiGe BiCMOS process offers superior noise characteristics compared to standard CMOS alternatives. Consider the 3x3 mm QFN footprint for compact PCB layouts requiring high-density interconnects.

Part Context

This device belongs to the Hittite (now Analog Devices) RF and microwave integrated circuits portfolio. It serves as a critical building block in high-performance frequency generation systems, bridging the gap between reference oscillators and higher frequency multipliers or mixers in complex signal chains.

Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. No direct substitutes are confirmed in the provided data; ensure functional compatibility regarding division ratios and operating frequency ranges before considering alternative components.
