Push-Pull Transmitter Circuit with Reflection Signal Attenuator for Communication System
Summary
USPTO published patent application US20260100866A1 for a push-pull transmitter circuit with integrated reflection signal attenuator for communication systems. The invention by Tasuku Yuguchi and Naoki Inoue includes rectifier elements and voltage cap elements designed to isolate reflection signals from communication signals. The application (No. 19330786) was filed September 16, 2025.
What changed
USPTO published patent application US20260100866A1 for a communication system incorporating a push-pull transmitter circuit with a reflection signal attenuator circuit. The invention uses first and second rectifier elements connected to high-side and low-side drive elements, along with voltage cap elements providing capping voltages of approximately 1.5 to 3 times the HIGH level voltage boundaries.
Affected parties including manufacturers of communication equipment, semiconductor companies, and electronics firms may find this published application relevant for prior art searches, freedom-to-operate assessments, and competitive intelligence monitoring. The publication represents an early-stage intellectual property filing that does not yet confer any enforceable rights.

Abstract
The communication system includes a push-pull transmitter circuit (2) that includes a reflection signal attenuator circuit (10) configured to keep the reflection signals outside of the amplitude direction of communication signals to prevent contamination thereof. The reflection signal attenuator circuit (10) includes first and second rectifier elements (D1 and D2) connected in series to a high-side drive element and a low-side drive element (Q1 and Q2), respectively, to prevent the reflection signals from the communication signals from flowing back to a power supply side, and first and second voltage cap elements (ZD1 and ZD2) connected in parallel to the high-side drive element and the low-side drive element (Q1 and Q2), respectively, to provide (add or subtract) capping voltages equal to approximately 1.5 to 3 times upper or lower boundaries for a HIGH level voltage of the communication signals when passing the reflection signals from the communication signals therethrough.
