HMC485MS8GE

RF Mixers Overview

The HMC485MS8GE is a high-linearity RF mixer IC manufactured by Analog Devices Inc., designed for up/down conversion applications. It operates within a frequency range of 1.7 GHz to 2.4 GHz. The component features an integrated local oscillator (LO) amplifier and delivers high third-order intercept point (IP3) performance, making it suitable for demanding wireless communication systems. It is housed in an 8-lead MSOP package with an exposed pad for thermal management.

RF Mixers Feature Summary

• High linearity performance with elevated IP3 specifications
• Compact surface-mount packaging with thermal pad

RF Mixers Applications

• W-CDMA systems
• CDMA infrastructure
• GSM base stations
• UMTS applications

RF Mixers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package variant. Check current lifecycle status as this part may be subject to discontinuation notices. Ensure ESD handling protocols are followed during storage and assembly. Validate datasheet revisions against the specific production batch date code.

RF Mixers Selection Notes

Select this component when high dynamic range and linearity are critical for receiver front-end stages. The integrated LO amplifier reduces external component count compared to passive mixers. Consider the 1.7–2.4 GHz operational window for compatibility with standard cellular bands. Evaluate thermal dissipation requirements due to the exposed pad design in the MSOP package.

RF Mixers Part Context

This device belongs to the Hittite Microwave Corporation product line, now integrated into Analog Devices Inc.'s portfolio following acquisition. The HMC series typically targets high-performance microwave and RF applications requiring compact form factors. The MS8GE suffix indicates a lead-free, halogen-free RoHS-compliant version in the MSOP-EP package.

RF Mixers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the integrated LO amplifier and specific high-IP3 characteristics, direct pin-to-pin replacements may require careful verification of electrical parameters and thermal performance.
