HMC551LP4

RF Mixers Overview

The HMC551LP4 is a GaAs MMIC double-balanced mixer operating from 0.8 to 1.2 GHz. It features an integrated LO amplifier and delivers high linearity with a +27 dBm input intercept point. Key electrical parameters include a maximum conversion loss of 10 dB and a noise figure of 8 dB. The device operates on a single 5 V supply with a current consumption of 62 mA. It is housed in a 24-lead QFN (4x4 mm) surface-mount package suitable for wireless applications.

RF Mixers Procurement Notes

Verify component status carefully as the HMC551LP4 is listed as obsolete or discontinued by major distributors. Confirm availability through authorized channels or secondary markets if sourcing is required. Check RoHS compliance details against specific revision requirements. Ensure replacement strategies are evaluated due to end-of-life status.

RF Mixers Selection Notes

Select this component for designs requiring high IP3 performance within the 0.8–1.2 GHz range. Consider the integrated LO amp simplifies drive requirements. Evaluate thermal management for the QFN package given 600 mW power dissipation. Verify compatibility with existing 5V supply rails and 62mA current budget in the target system design.
