HMC525-EGM

RF Mixers Overview

The HMC525-EGM is a GaAs MMIC I/Q mixer designed for operation between 4.0 GHz and 8.5 GHz. It functions as an image rejection mixer or single-sideband upconverter, utilizing two double-balanced mixer cells and a 90-degree hybrid. The device requires no DC bias. Typical conversion loss is 8 dB, with image rejection of 40 dB and LO-to-RF isolation of 50 dB. It features a high input IP3 of +23 dBm and supports a wide IF bandwidth from DC to 3.5 GHz.

RF Mixers Feature Summary

• Passive operation requiring no DC bias voltage
• Integrated 90-degree hybrid for image rejection functionality
• High linearity performance with +23 dBm input IP3
• Compact die package suitable for space-constrained designs

RF Mixers Applications

• Point-to-point radio systems
• Point-to-multi-point radio links
• VSAT communication terminals

RF Mixers Procurement Notes

Verify the specific suffix (EGM) against official Analog Devices documentation to confirm the exact die configuration and pad arrangement. Ensure compatibility with existing RF layout requirements, as this component is a bare die requiring precise mounting. Cross-reference the datasheet revision date to ensure all electrical parameters match your design specifications before finalizing procurement.

RF Mixers Selection Notes

Select this component when designing passive mixers for the 4–8.5 GHz range that require high image rejection without active biasing. It is suitable for applications demanding high linearity (+23 dBm IP3) and wide IF bandwidth (DC–3.5 GHz). Consider the bare-die format for integration into custom PCBs or multi-chip modules where size constraints are critical.

RF Mixers Part Context

The HMC525-EGM belongs to the Hittite Microwave (now Analog Devices) family of GaAs MMIC mixers. It is part of a series offering compact I/Q mixing solutions. This specific variant is a bare die, distinct from packaged versions like the HMC525ALC4. It leverages MESFET technology to provide robust RF performance in a minimal footprint for microwave applications.
