7.1 Overview

The LMH9135 device is a differential input to single-ended output narrow-band RF amplifier used in transmitter applications. The device provides 18 dB fixed power gain with excellent linearity and noise performance across the frequency band 3.2 – 4.2 GHz. The device is internally matched for 100-Ω impedance at the differential input and 50-Ω impedance at the single-ended output, as shown in Figure 7-1.

LMH9135 have 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 saving 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 applications.

Operating on a single 3.3 V supply and 120 mA of typical supply current, the devices are available in a 2 mm x 2 mm 12-pin QFN package.
