LMH9235IRRLR

Overview

The LMH9235IRRLR is a single-channel, single-ended input to differential output RF gain block amplifier manufactured by Texas Instruments. It operates within the frequency range of 3.3 GHz to 4.2 GHz and supports the 3.3 GHz to 3.8 GHz band directly. The device utilizes a WQFN-12 (2x2) package and functions on a 3.3 V supply. Key electrical characteristics include a noise figure of 3 dB, a P1dB compression point of 17.5 dBm, and an OIP3 of 35 dBm at a test frequency of 2.6 GHz. It consumes 84 mA of current with a power dissipation of 275 mW.

Feature Summary

• Single-ended to differential conversion for simplified system architecture
• Low distortion performance suitable for sensitive signal detection
• Precise temperature compensation mechanism for stable operation
• Fully compatible with existing infrastructure designs

Applications

• Next generation 5G Active Antenna Systems (AAS)
• Small cell base station implementations
• General purpose RF amplification in wireless communications

Procurement Notes

Verify the specific suffix IRRLR corresponds to the WQFN-12 package and reel packaging configuration. Confirm that the operating voltage and frequency range align with your system requirements before integration. Ensure ESD protection measures are observed during handling due to the sensitivity of RF components.

Selection Notes

Select this component when a single-ended to differential interface is required for frequencies between 3.3 GHz and 4.2 GHz. It is appropriate for applications demanding low noise and high linearity in compact form factors. Consider the thermal management capabilities of the WQFN-12 package relative to the 275 mW power dissipation in your design.

Part Context

This part belongs to the LMH9226 series of RF amplifiers from Texas Instruments. While similar devices like the LMH9226 operate at lower frequencies (2.3–2.9 GHz), the LMH9235 is optimized for higher frequency bands up to 4.2 GHz. Both share the same package type and general functionality as gain block amplifiers.
