7.1 Overview

The LMH9226 is single-ended, 50-Ω input to differential 50-Ω or 100-Ω output RF gain block amplifier used in 2.3-GHz to 2.9-GHz, frequency-band, 5G, m-MIMO TDD receiver applications. The device provides a 17-dB fixed power gain with excellent linearity and noise performance across 400 MHz of the 1-dB bandwidth at the 2.6-GHz center frequency. The device is internally matched for a 50-Ω input impedance at 2.6 GHz. The device differential output can be matched to the 50-Ω impedance without external matching circuitry, or to the 100-Ω impedance with external matching circuitry (see the Application and Implementation section for details). The device is typically used in the final stage of a receive signal chain to drive the differential input of an analog-to-differential converter (ADC), while providing additional gain to a low-noise amplifier (LNA) to increase dynamic range and the required single-ended to differential conversion.

The LMH9226 has an on-chip active bias circuitry to maintain device performance over a wide temperature and supply voltage range. The included power-down function allows the amplifier to shut down and save power when the amplifier is not needed. Fast shut-down and start-up enable the amplifier to be used in a host of time division duplex (TDD) applications.

Operating on a single 3.3-V supply and consuming 84 mA of typical supply current, the device is available in a
2-mm × 2-mm, 12-pin WQFN package.
