Latest Patents

Carlile's latest patents include two innovative designs for balanced low-pass common mode filters. The first patent describes a balanced L-section low-pass common mode filter that is connected in series with balanced data I/O lines. This filter effectively removes common mode signals from balanced line difference mode signals. It features input and output series transformers that are configured to ensure that the magnetic fields in the transformers are subtractive for out-of-phase difference mode signals and additive for in-phase common mode signals. Additionally, a shunt transformer coupled to ground is designed to enhance the filter's performance by ensuring that the difference mode signals remain unaffected while common mode signals are attenuated.

The second patent outlines a balanced T-section low-pass common mode filter, which operates on similar principles. This filter is also connected in series with balanced data I/O lines to eliminate common mode signals. The configuration of the transformers in this design mirrors that of the L-section filter, ensuring optimal performance in filtering out unwanted signals while preserving the integrity of the desired data transmission.
