The PSPL5320B 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 PSPL5320B has a fast 31 ps rise time and a bandwidth from 5 kHz to 11 GHz. The PSPL5320B can also be used as an algebraic differential signal combiner. All three ports are matched to 50 Ω.
