The Astronics/Ballard Technology 17011 is a 1-stub transformer coupler for MIL-STD-1553 data bus applications in aerospace and defense systems. This component provides dual bus interfaces and a single stub interface via transformer-based coupling, delivering signal integrity and distortion minimization critical to military avionics and defense communications. The 17011 couples directly to MIL-STD-1553B compliant buses and integrates with standard twinax cabling and terminator networks.
## Technical Specifications
The 17011 conforms to MIL-STD-1553B standards and MIL-PRF-21038/27 transformer coupler specifications. The transformer coupling architecture delivers a 1:√2 turns ratio with 57 ohm series resistors and 77.5 ohm characteristic impedance, optimizing impedance matching and signal fidelity on the bus. The unit features dual bus interface points and a single stub connection, enabling flexible multi-node network topologies.
