Overview

The LMH9126 device is a differential input to single-ended output narrow-band RF amplifier that is used in transmitter applications. The device provides 18-dB fixed power gain with excellent linearity and noise performance across 1-dB bandwidth of the 2.6-GHz center frequency. The device is internally matched for 100-Ω differential impedance at the input and 50-Ω impedance at the output, as shown in Figure 16.

The LMH9126 has on-chip active bias circuitry to maintain device performance over a wide temperature and supply voltage range. The included power down (PD) function allows the amplifier to shut down. The PD function is useful to save power when the amplifier is not needed and also allows to mute the transmitter when in receive mode. Fast shut down and start up enable the amplifier to be used in a host of TDD applications.

Operating on a single 3.3-V supply and 114 mA of typical supply current, the devices are available in a 2-mm × 2-mm 12-pin QFN package.
