Impulse Forming Networks
PSPL5208, PSPL5210 Datasheet
These components are proprietary, passive Impulse Forming
Networks (IFNs). They have the unique property of providing an
output that is approximately the derivative of the input waveform
while also maintaining an excellent impedance match on all ports.
V(out) ≈ Tc * dV(in) / dt
W here Tc is the derivative time coefficient. When driven by a step,
the output is an impulse. When driven by an impulse, the output is a
monocycle. The various models are optimized for use with different
input risetimes. A third IFN port is labeled “DC” and terminated in 50 Ω. A DC baseline offset,
bias voltage, and/or a slower risetime, pedestal pulse may be connected to this DC port.
