Application Notes
The Specialty Components Division has developed a high frequency BALUN
speed applications such as Fibre Channel, Gigabit Ethernet and next generafor test and measurement applications. Wide bandwidth and high frequency tion MIL-STD-1553. The BALUN allows design engineers to characterize difresponse makes thisdevice ideal for differential mode measurement in high ferential 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.
