LMH9126IRRLR

Overview

The LMH9126IRRLR is a high-performance, single-channel RF gain block amplifier manufactured by Texas Instruments. It features a differential input to single-ended output architecture with an integrated balun, designed for the 2.3 GHz to 2.9 GHz frequency band. The device operates on a 3.3 V supply with a typical current consumption of 114 mA. Key electrical specifications include a gain of 18 dB, a noise figure of 3.5 dB, a P1dB compression point of 18 dBm, and an OIP3 of 36 dBm. It is housed in a 12-WQFN package and supports operating temperatures from -40°C to +105°C.

Feature Summary

• Integrates a balun to convert differential signals to single-ended outputs
• Provides high linearity with an OIP3 of 36 dBm
• Supports wide temperature operation from -40°C to +105°C

Applications

• GPS receiver front-ends
• Wireless communication systems
• RF signal processing chains

Procurement Notes

Verify the complete part number including the suffix 'RR' which indicates reel packaging. Confirm the manufacturer is Texas Instruments. Check datasheet revision dates for accuracy. Ensure the WQFN-12 package matches design requirements. Validate RoHS compliance status before ordering.

Selection Notes

Select this component for applications requiring differential-to-single-ended conversion within the 2.3–2.9 GHz range. Consider the 18 dB gain and 3.5 dB noise figure for signal integrity. Evaluate the 114 mA supply current against power constraints. Ensure the 12-WQFN footprint fits the PCB layout.

Part Context

This device belongs to Texas Instruments' family of high-performance RF amplifiers. It is specifically engineered for transmit and receive paths in wireless infrastructure. The integration of the balun reduces component count compared to discrete solutions. It complements other RF blocks in modern communication modules.
