HMC8191-SX

RF Mixers Overview

The HMC8191-SX is a passive broadband I/Q mixer from Analog Devices Inc., designed for RF and IF applications. It operates within a frequency range of 6 GHz to 26.5 GHz, supporting both up-conversion and down-conversion tasks. The device features a wide intermediate frequency (IF) bandwidth extending from DC to 5 GHz. It utilizes single-ended RF, LO, and IF ports for simplified circuit integration. Typical performance specifications include a conversion loss of 9 dB, an image rejection of 25 dBc, and a single-sideband noise figure of 9 dB. The component is supplied in a die package format.

RF Mixers Feature Summary

• Supports dual I/Q mixing functions for up-conversion and down-conversion
• Features wide intermediate frequency bandwidth from DC to 5 GHz
• Utilizes single-ended RF, LO, and IF port configurations
• Provides high image rejection capabilities typical of 25 dBc

RF Mixers Applications

• RF and IF signal processing systems
• RFID application architectures
• Wideband communication transceivers

RF Mixers Procurement Notes

Verify the specific suffix 'SX' indicates the die package configuration rather than the standard CLCC surface mount variant. Confirm that the intended design supports bare die handling procedures and appropriate substrate mounting techniques required for this form factor. Ensure compatibility with the specified 6 GHz to 26.5 GHz operational range for the target application requirements.

RF Mixers Selection Notes

Select this component when a wideband I/Q mixer is required for frequencies between 6 GHz and 26.5 GHz. Consider the die package format if space constraints or custom assembly processes are necessary. Evaluate the typical 9 dB conversion loss and 9 dB noise figure against system link budget requirements. Ensure the design can accommodate the single-ended port topology without additional balancing networks.

RF Mixers Part Context

The HMC8191 series includes variants such as HMC8191LC4 and HMC8193, which share similar functional characteristics but differ in packaging. The LC4 version utilizes a 24-lead CLCC surface mount package, whereas the SX suffix denotes the die configuration. These mixers are part of Analog Devices' portfolio of MMIC components designed for high-performance microwave applications.

RF Mixers Replacement Considerations

HMC8193LC4 is documented as a similar alternative to the discontinued HMC620, though it differs in frequency range and package type. Direct replacement requires verifying package compatibility and electrical parameter alignment between the die and surface mount variants.
