17 GHz Differential Pulse Splitter
PSPL5315A Datasheet
The PSPL5315A BALUN is a broadband differential pulse
splitter. A signal fed into the 50 Ω input is split equally into
two 50 Ω outputs. One output is the same polarity as the
input, while the other output is inverted in polarity. The
PSPL5315A BALUN has a very fast 21 ps risetime and a
bandwidth of 17 GHz. One application of the PSPL5315A is to provide push-pull, balanced drive signals
for the deflection plates of ultra-wideband, traveling-wave oscilloscopes.

Note: All parameters listed are typical unless max/min guaranteed limits are provided. Due to
internal reflections, the 5315A is NOT recommended for use with gigabit logic signals nor in a
differential network analyzer.

T he end of the non-inverting output may not lie in
precisely the same plane as the end of the inverting
output. The non-inverting line length is adjusted so
that the output phases differ by 180°.
