HMC422MS8E

RF Mixers Overview

The HMC422MS8E is a double-balanced mixer IC featuring an integrated local oscillator amplifier, manufactured by Analog Devices Inc. It operates within a frequency range of 1.2 GHz to 2.6 GHz and supports both upconversion and downconversion applications. The device requires only 0 dBm LO drive level due to the internal amplifier. It is supplied in an 8-MSOP package with a width of 3.00 mm. The component is designed for CATV systems and utilizes a single supply voltage.

RF Mixers Feature Summary

• Integrates a local oscillator amplifier to eliminate external LO driver requirements
• Double-balanced architecture provides high isolation between ports
• Supports flexible operation as either an upconverter or downconverter

RF Mixers Applications

• CATV headend and remote node frequency conversion
• RF signal chain upconversion stages
• RF signal chain downconversion stages

RF Mixers Procurement Notes

Verify current lifecycle status as the HMC422 series may be obsolete. Confirm package compatibility with 8-MSOP footprints. Check for available replacement parts from Analog Devices if production continuity is required. Ensure supply voltage and current consumption meet system constraints. Validate datasheet specifications against latest revision before integration.

RF Mixers Selection Notes

Choose this component when low LO drive power is critical to simplify RF front-end design. The integrated amplifier reduces bill of materials and board space compared to discrete mixer solutions. Consider the 1.2 GHz to 2.6 GHz operating range for suitability in CATV and broadband applications. Evaluate thermal performance within the 8-MSOP package for dense layouts.

RF Mixers Part Context

The HMC422MS8E belongs to Analog Devices' HMC422 family of double-balanced mixers. This series is characterized by its monolithic integration of the mixer core and LO amplifier. The MS8 suffix denotes the 8-lead Mini-SOP surface-mount package. The E variant typically indicates environmental compliance or specific manufacturing lot characteristics defined by the manufacturer.
