Application Notes:
The Specialty Components Division has developed a high
frequency BALUN for test and measurement applications.
Wide bandwidth and high frequency response makes this
device ideal for differential mode measurement in high
speed applications such as Fibre Channel, Gigabit Ethernet
and next generation MIL-STD-1553. The BALUN allows
design engineers to characterize differential mode devices
using single-ended test equipment as shown below.

Insertion loss S21 is measured with two units connected back to back as shown.
Note 1: Correct value of S21 for each DUT will be 1/2 of the value shown in graph.
Note 2: Return loss S11 is measured on 50 ohm port with 150 ohms termination on balance port.
