1553 Data Bus Transformers

Ferrtx 1553 Bus Couplers are precision-engineered components designed for reliable signal coupling in MIL-STD-1553 and 1553B data bus networks.
As high-performance Data Bus Coupling Transformers, they ensure stable signal integrity, controlled impedance, and reinforced isolation in mission-critical communication systems.

These products are widely used in avionics, military electronics, and aerospace platforms where robustness and compliance are essential.

What Is a 1553 Bus Coupler?

A 1553 Bus Coupler is a passive coupling device used to connect terminals (RT, BC, or MT) to the main MIL-STD-1553 data bus without disturbing overall bus impedance.

Ferrtx 1553B Data Bus Couplers integrate precisely matched coupling transformers and resistive networks to:

• Isolate terminals from the main bus

• Maintain standard 70–85Ω bus impedance

• Protect the bus from terminal faults

• Preserve signal integrity under harsh environments

Data Bus Coupling Transformers – Core Functionality

At the heart of every 1553 bus coupler is a Data Bus Coupling Transformer.
These transformers are designed to:

• Provide galvanic isolation between terminal and bus

• Ensure balanced signal coupling

• Minimize reflections and insertion loss

• Withstand high transient voltages

Ferrtx coupling transformers are manufactured with controlled winding symmetry and high-reliability Magnetic Cores to meet aerospace and defense requirements.
