Procurement Notes

Verify the specific suffix (ETR) indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact x8 multiplier specification. Check for RoHS compliance status as indicated in official documentation. Validate that the component is suitable for the intended operating temperature range.

Selection Notes

Select this component when an x8 multiplication ratio is required at frequencies near 10 GHz. Consider the InGaP GaAs HBT technology for specific linearity and noise characteristics. Evaluate the 24-pin QFN EP package for PCB space constraints. Compare against other multipliers in the HMC series if different multiplication ratios are needed.

Part Context

This part belongs to the HMC444 series of active frequency multipliers from Analog Devices. It is distinct from similar models like the HMC443, which offers a different multiplication ratio. The series focuses on providing integrated solutions for millimeter-wave applications using advanced semiconductor processes.
