HMC128

RF Mixers Overview

The HMC128 is a miniature double-balanced mixer chip manufactured by Analog Devices Inc. It functions as a passive diode/balun type mixer suitable for upconversion or downconversion applications. The device operates within an RF frequency range of 1.8 GHz to 5 GHz and supports LO frequencies from 1.8 GHz to 5.0 GHz. The intermediate frequency (IF) range extends from DC to 3 GHz. Key electrical specifications include a maximum conversion loss of 10 dB and a noise figure of 10 dB. The component is available in a hermetic surface mount package designated as HMC128G8, featuring an 8-SMT configuration.

RF Mixers Procurement Notes

Verify the specific ordering suffix when sourcing this component, as the base part number refers to the chip while the G8 suffix denotes the hermetic surface mount package. Confirm current availability status, as distribution channels may list this item as discontinued or obsolete depending on regional inventory. Ensure that the received unit matches the required package type for your PCB layout constraints. Cross-reference the manufacturer's official documentation for the most accurate pinout and mechanical dimensions before finalizing procurement orders.

RF Mixers Selection Notes

Select the HMC128 when a compact, passive double-balanced mixer solution is required for frequencies between 1.8 GHz and 5 GHz. Consider its 10 dB conversion loss and 10 dB noise figure against system sensitivity requirements. The choice depends on whether a chip form factor or the hermetic SMT package is preferred for environmental protection. Evaluate the IF bandwidth capability up to 3 GHz to ensure compatibility with the desired signal processing architecture.

RF Mixers Part Context

The HMC128 belongs to the Hittite Microwave Corporation product line, now integrated into Analog Devices Inc. following acquisition. It is part of a family of miniature MMIC mixers designed for high-performance RF applications. The device represents a transition from traditional discrete mixer designs to integrated monolithic solutions, offering reduced size and improved consistency in manufacturing processes for wireless communication systems.
