Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance requirements as the listed specification indicates non-compliance. Ensure the SOT-23-6 package matches your PCB footprint design constraints before finalizing procurement decisions.

Selection Notes

Select this component when a divide-by-4 prescaler is required for frequencies extending to 8 GHz. Consider the 53 mA operating current and -2 dBm output power levels against system power budgets. Verify that the SMD/SMT mounting style aligns with your assembly capabilities and thermal management strategies.

Part Context

This prescaler belongs to Analog Devices' family of wireless and RF integrated circuits. It serves as a critical frequency division stage in phase-locked loop architectures. The device complements other development tools like the DC1075B-C which utilizes similar divider technologies for evaluation purposes.

Replacement Considerations

The ADMV2101BRHZ-R7 is a documented substitute part number offering similar divide-by-4 functionality. Verify interface compatibility and pinout alignment before substitution.
