It can also be used as a pulse transformer with very fast pulses (typical rise time: 0.5 ns). The transformer operates as either a signal splitter or a signal combiner. As a signal splitter, the transformer provides two identical output signals (which are in phase with each other) from a single input. Each of the two output signals is 3 dB down from the input signal (half the power of the input signal). There is a high degree of separation or transhybrid loss between the two output signals. As a signal combiner, the transformer provides a single output signal from two identical input signals (which are in phase with each other). The output signal has twice the power of either input signal.
