7.3 Feature Description

The LMH9126 device is a differential to single-ended RF amplifier for narrow band active balun implementation. The device integrates the functionality of a passive balun and a single-ended RF amplifier in traditional transmitter applications achieving small form factor with comparable linearity and noise performance, as shown in Figure 17.

The active balun implementation coupled with higher operating temperature of 105°C allows for more robust system implementation compared to passive balun that is prone to reliability failures at high temperatures. The robust operation is achieved by the on-chip active bias circuitry which maintains device performance over a wide temperature and supply voltage range.
