17 GHz Differential Pulse Splitter PSPL5315A Datasheet The PSPL5315A BALUN is a broadband differential pulse splitter. A signal fed into the 50 input is split equally into two 50 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.
