The PSPL5315 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 PSPL5315 BALUN has a very fast 21 ps rise time and a bandwidth of 17 GHz. One application of the PSPL5315 is to provide push-pull, balanced drive signals for the deflection plates of ultra-wideband, traveling-wave oscilloscopes.
