HMC528LC4

RF Mixers Overview

The HMC528LC4 is a GaAs MMIC I/Q mixer with Image Rejection Mixer (IRM) functionality, operating in the 11 GHz to 16 GHz RF and LO frequency range. It provides an IF output from DC to 3.5 GHz. Key electrical specifications include a maximum conversion loss of 12 dB and high input IP3 values of 27 dBm for this specific variant. The device is housed in a compact 4 mm × 4 mm leadless RoHS-compliant SMT QFN-24 package. It supports a maximum power dissipation of 448 mW and functions within a temperature range of -55°C to +85°C.

RF Mixers Feature Summary

• Test and measurement instrumentation equipment

RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm lot traceability and RoHS compliance documentation upon receipt. Inspect packages for physical damage due to moisture sensitivity requirements. Ensure proper ESD handling protocols are followed during storage and installation. Cross-reference datasheet revisions to confirm current manufacturing status and parameter tolerances.

RF Mixers Selection Notes

Select this component when image rejection is critical in the 11–16 GHz band. Compare conversion loss and IP3 against system noise floor requirements. Evaluate the 4x4 mm footprint against PCB space constraints. Consider the DC to 3.5 GHz IF bandwidth for downstream signal processing needs. Assess thermal dissipation capabilities relative to enclosure airflow conditions.

RF Mixers Part Context

This part belongs to the HMC528G series of general-purpose I/Q mixers. It complements other variants like the HMC523LC4 which operates at higher frequencies (15–23 GHz). The LC4 suffix denotes the specific leadless QFN-24 package configuration. These devices represent Analog Devices' integration of RF mixing functions into small monolithic circuits.
