Abstract
A high bandwidth data interface in an aircraft includes a pulse tolerant, non-inductive resistor for reducing surge current due to lightning transients, and a very low capacitance transient voltage suppressor to suppress the lightning transient voltages. A cable equalizer/redriver then recovers the original high bandwidth input signal. The high bandwidth interface is thereby able to survive DO-160 section 22 level 3 and 4 lightning transients.
Claims16
A transient voltage suppression circuit comprising:
- an ultra-low capacitance transient voltage suppressor;
- and
- a cable equalizer in electronic communication with the transient voltage suppressor,
- wherein:
- the transient voltage suppressor is configured to remove lightning transients from a signal having at least one gigahertz bandwidth;
- and
- the cable equalizer is configured to boost a filtered signal from the transient voltage suppressor.
