RF Coaxial Connectors
Telecom Balun
The ITT Industries, Cannon 1.0/2.3 Telecom Balun, for use in ITU G.703 applications, converts
between a 120 ohm twisted pair and a 75 ohm coaxial transmission line.
This connector has a 1.0/2.3 Push-Pull plug interface with the transformer built into the body,
it can be quickly connected to screened or unscreened twisted pair cables through IDC
terminations, using a simple assembly tool. The small size allows these connectors to be
mounted on a pitch of 10 mm.
This balun is ideal for use where it is necessary to interconnect an equipment with 75 ohm
coaxial outputs to a 120 ohm cable distribution system. The balun is only a little larger than
the connector that it would replace.
