Notes
[1] Parameters listed are typical values. Guaranteed only when max/min limits are given.
[2] 10 ps risetime step response and TDR waveform measured using a PSPL Model 4015B pulse generator and an HP-54124A
50 GHz, 9.4 ps digital sampling oscilloscope.
[3] Frequency response measured using a Wiltron 5447A 10 MHz - 20 GHz network analyzer.
[4] Due to internal reflections, the 5315A is NOT recommended for use with GigaBit logic signals nor in a differential network
analyzer. For details, see PSPL Application Note AN-9.

The Model 5315A BALUN is a broadband differential
pulse splitter. A signal fed into the 50 W input is split
equally into two 50 W outputs. One output is the same
polarity as the input, while the other output is inverted
in polarity. The 5315A BALUN has a very fast 21 ps
risetime and a bandwidth of 17 GHz. One application of the 5315A is to provide push-pull, balanced
drive signals for the deflection plates of ultra-wideband, traveling-wave oscilloscopes.
