SKEWED HYBRID MODULE
The Skewed Hybrid Module uses two hybrid transformers to connect a transmitter and receiver to a
single line tuning port. The Skewed Hybrid provides a high degree of signal separation by isolating the
local transmitter signal from the local received signal and preventing the input impedance of the
receiver from loading the transmitter. The impedance characteristics of the two types of Skewed-
Hybrid modules is shown in the table below.

SPECIFICATIONS
As of the date this manual was published, the following specifications apply to all Skewed Hybrid
Modules, except where indicated. Because all RFL products undergo constant refinement and
improvement, these specifications are subject to change without notice.
Insertion Loss (60 to 500 kHz):
Transmitting: Approximately 0.3 dB.
Receiving: Approximately 12.5 dB.
Transhybrid Loss (60 to 500 kHz):
Greater than 40 dB when operating with the specified termination impedance.
Internal Balance Range:
0.5 to 1.95 times the specified two-wire impedance.
Power Capacity:
10 Watts rms.
Two-Wire Line Impedance:
50 Ohms standard; other impedances are available on special order.
Second Harmonic Distortion:
At least 80 dB below the fundamental frequency.
Third Order Intermodulation Products:
At least 60 dB below the fundamental frequency.
