Undervoltage protection diode (D2)
During a short-circuit event on the LNB output, negative voltage spikes may occur on the
VoRX pin. To prevent reliability problems, a low-cost Schottky diode with low VF clamping
voltage is used between this pin and GND (see D2 in Figure 6). It is recommended to place
the protection diode cathode as close as possible to the VoRX pin.
