HMC528

RF Mixers Overview

The HMC528 is a compact I/Q MMIC mixer fabricated in a GaAs MESFET process. It utilizes two standard double balanced mixer cells and a 90-degree hybrid to function as an Image Reject Mixer (IRM) or Single Sideband Upconverter. The device operates within the 11 GHz to 16 GHz frequency range. Key electrical parameters include a wide IF bandwidth from DC to 3.5 GHz, image rejection of 35 dB, LO to RF isolation of 45 dB, and a high input IP3 of +27 dBm.

RF Mixers Feature Summary

• Integrates dual balanced mixer cells with a quadrature hybrid for I/Q signal processing
• Provides high image rejection performance suitable for complex modulation schemes
• Delivers high linearity indicated by elevated input IP3 specifications

RF Mixers Applications

• Point-to-Point Radio Systems
• Point-to-Multi-Point Radio Networks
• Military Radar Applications

RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices channels. Confirm package type requirements, as the HMC528 is available as a bare die requiring specific mounting fixtures. Ensure compatibility with 50 Ohm test environments if evaluating datasheet parameters directly. Check current availability status as manufacturing transitions may affect supply continuity.

RF Mixers Selection Notes

Select this component when space-constrained IRM or SSB upconversion is required in the 11-16 GHz band. Consider the GaAs MESFET technology for its balance of noise and linearity. Evaluate the need for external filtering given the wide IF bandwidth capability. Assess thermal management requirements for the bare die configuration during system integration.

RF Mixers Part Context

The HMC528 belongs to the Hittite Microwave Corporation family of RF mixers, now part of Analog Devices Inc. It serves as a compact alternative to larger hybrid-style assemblies. The device represents a specialized solution for high-frequency communication systems requiring precise sideband suppression and isolation characteristics.

RF Mixers Replacement Considerations

The HMC528LC4 is a leadless RoHS-compliant SMT package variant of the same functional core. Verify pinout and thermal pad configurations when substituting between the bare die and surface mount versions.
