LMX2216MX

Overview

The LMX2216MX is a monolithic integrated circuit combining a low noise amplifier (LNA) and a mixer, designed for RF personal communications applications. It operates within a frequency range of 0.1 GHz to 2.0 GHz. The device is housed in a 16-lead SOIC surface-mount package. It serves as a first-stage amplifier and down-conversion mixer, offering high performance for cellular, WLAN, PCS, PHS, and cordless phone systems.

Feature Summary

• Integrates a low noise amplifier and mixer into a single monolithic chip
• Suitable for use as a first-stage amplifier and down-conversion mixer
• Designed specifically for RF personal communications systems

Applications

• Cellular phone systems
• Wireless LAN (WLAN) infrastructure
• Personal Communications Service (PCS) devices
• PHS (Personal Handy-phone System) terminals
• Cordless phone applications

Procurement Notes

Verify the manufacturer origin and date code upon receipt, as sources indicate potential variations including China origin and specific date codes like 26+. Confirm the package type is 16-SOIC surface mount. Ensure the component matches the Texas Instruments or National Semiconductor lineage documentation for the LMX2216 series. Check for RoHS compliance status if required by your assembly specifications.

Selection Notes

Select this component when a combined LNA and mixer solution is required for frequencies between 100 MHz and 2 GHz. It is appropriate for designs needing a compact, single-chip approach for first-stage amplification and down-conversion in personal communication devices. Consider the 16-SOIC package constraints for PCB layout. Evaluate system noise figure requirements against the integrated LNA performance.

Part Context

The LMX2216MX belongs to the LMX22xx series of RF components originally developed by National Semiconductor, which was acquired by Texas Instruments. This series includes various synthesizers and mixers for personal communications. The MX suffix typically denotes the SOIC package variant. It is part of a broader family of PLLatinum and RF front-end solutions used in wireless handsets and base stations.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Similar functions may be found in other LMX series devices such as the LMX2324 or LMX2240, but these serve different roles like frequency synthesis or intermediate frequency reception. Direct replacement requires verification of pin compatibility and electrical specifications against official datasheets.
