APPLICATIONS NOTES
The S553-6500-93 hybrid transformer operates
with 75 terminations over an extremely wide
frequency spectrum (3 dB response: 20 kHz to
800 MHz).
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 trans-
former 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 trans-
former 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.
