Hybrids are optional modules for the RFL Powerline Carrier equipment. They may be used to combine
combinations of transmitters and receivers to a single port for connection to line tuning units. There is
an X-Hybrid Module and a Skewed Hybrid Module available. Each of these modules uses the same
basic printed circuit board.
The Auxiliary Hybrid Chassis shown in Figure 1 is used to add X-Hybrid modules or Skewed Hybrid
modules to RFL Powerline Carrier systems. Each Auxiliary Hybrid is contained in a 19-inch chassis
that occupies less than one rack unit of vertical rack space (1.718 inches, or 4.4 cm). Each chassis can
accommodate three Hybrid modules and three Hybrid I/O modules. The Hybrid modules are mounted
in the front of the chassis, and the Hybrid I/O modules are mounted at the rear of the chassis. In a
given chassis the Hybrid modules can be a mix of any combination of X-Hybrid modules or Skewed
Hybrid modules.

75 Ohms SPECIFICATIONS As of the date this manual was published, the following specifications apply to all X-Hybrid Modules, except where indicated. Because all RFL products undergo constant refinement and improvement, these specifications are subject to change without notice. Insertion Loss: Approximately 3.5 dB, either input port to line output port. -

The X hybrid can also be used to connect two transmitters to the same line tuning unit, resulting in dual-channel transmission capabilities. In this application, one transmitter is connected across the primary of L1 , and the other transmitter is connected across the primary of L2. RFL Auxiliary Hybrid Chassis RFL Electronics Inc.
