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. Typical Return Loss - S11 Typical Insertion Loss - S21 50 ohm Unbalanced Port Two Baluns Configured Back to Back 2 dB/div Attenuation (dB) -15 dB Attenuation (dB) 0 dB .5 dB/div -4 dB 1.0 MHz Frequency (MHz) NETWORK ANALYZER CH-1 DUT #1 CH-2 1.0 MHz 1.2 GHz Frequency (MHz) 1.2 GHz 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.
