LMX2216M

Overview

The LMX2216M is a low noise amplifier and mixer designed for RF personal communications applications. It operates within a frequency range of 0.1 GHz to 2.0 GHz, supporting cellular, WLAN, PCS, PHS, and cordless phone systems. The device provides a gain of 9 dB to 10 dB with a noise figure between 4.8 dB and 6 dB. Its one-dB compression point (P1dB) ranges from -5 dBm to -3 dBm. Packaged in a 16-SOIC format, it integrates amplification and down-conversion capabilities suitable for intermediate frequency receiver stages.

Feature Summary

• Integrates low noise amplification and mixing functions in a single component
• Optimized for RF personal communication standards including cellular and WLAN
• Supports frequency coverage from 100 MHz to 2 GHz

Applications

• Cellular phone receivers
• WLAN infrastructure and devices
• PCS and PHS systems
• Cordless telephone base stations

Procurement Notes

Verify the manufacturer origin, as Texas Instruments acquired National Semiconductor. Confirm the package type matches the 16-SOIC specification. Ensure the part number suffix corresponds to the required tape and reel or bulk packaging options available from authorized distributors. Cross-reference datasheet revisions to confirm electrical parameter consistency.

Selection Notes

Select this component when a combined LNA and mixer solution is required for frequencies up to 2 GHz. Consider the noise figure and gain specifications relative to system sensitivity requirements. Evaluate the P1dB performance against input signal levels. Verify compatibility with intermediate frequency processing stages in the target RF architecture.

Part Context

This device belongs to the RF personal communications component family, historically associated with National Semiconductor before its acquisition by Texas Instruments. It serves as an alternative to discrete amplifier and mixer combinations, simplifying circuit design for mobile and wireless communication equipment requiring efficient signal conditioning.
