HMC551LP4E

RF Mixers Overview

The HMC551LP4E is a GaAs MMIC double-balanced mixer designed for RF applications between 800 MHz and 1.2 GHz. It features an integrated local oscillator amplifier and delivers high linearity with a +27 dBm input level. The device operates on a single 5V supply, drawing 62mA of current. Packaged in a compact 24-QFN (4x4) surface-mount format, it exhibits a maximum conversion loss of 10 dB and a noise figure of 8 dB. This component supports frequency up-conversion and down-conversion tasks within mobile, 3G, and GSM communication systems.

RF Mixers Procurement Notes

Verify the specific suffix 'E' to confirm RoHS compliance status, as manufacturing changes may affect environmental certifications. Check official Analog Devices notices for end-of-life or product discontinuation updates, as this component has been subject to EOL announcements. Ensure the 24-QFN package matches your PCB footprint requirements before ordering.

RF Mixers Selection Notes

Select this component when designing circuits requiring high IP3 performance in the 800 MHz to 1.2 GHz range. The integrated LO amplifier simplifies design by reducing external drive requirements. Consider the 8 dB noise figure and 10 dB conversion loss limits when calculating system link budgets for sensitive receiver or transmitter chains.

RF Mixers Part Context

This part belongs to the HMC551 series of high-linearity mixers from Analog Devices. It is functionally similar to the HMC551LP4 variant, with the 'E' suffix typically indicating environmental compliance. Both variants share identical electrical specifications and pinouts, serving as direct replacements in designs where lead-free or RoHS-compliant materials are mandated.

RF Mixers Replacement Considerations

HMC551LP4 is a confirmed functional substitute with identical electrical characteristics. Verify that the replacement unit meets the required RoHS standards if environmental compliance is critical for the final assembly.
