ZHCSLB8C May 2020 – May 2021 LMH9235
PRODUCTION DATA
7.3 Feature Description
The LMH9235 device is single-ended to differential RF amplifier for narrow band active balun implementation. The device integrates the functionality of a single-ended RF amplifier and passive balun in traditional receive applications achieving small form factor with comparable linearity and noise performance, as shown in Figure 7-2.
The active balun implementation coupled with higher operating temperature of 105°C allows for more robust receiver system implementation compared to passive balun that is prone to reliability failures at high temperatures. The high temperature operation is achieved by the on-chip active bias circuitry which maintains device performance over a wide temperature and supply voltage range.
