7.3 Feature Description

As shown in Figure 17, the LMH9226 integrates the functionality of a single-ended RF amplifier and passive balun in a traditional receive application, achieving a small form factor with good linearity and noise performance. The active balun implementation, along with a higher operating temperature of 105°C, allows for a more robust receiver system implementation compared to a passive balun that is prone to reliability failures at high temperatures. The high-temperature operation is achieved by the on-chip, active bias circuitry that maintains device performance over a wide temperature and supply voltage range.
