The PSPL5208 and PSPL5210 components are proprietary, passive Impulse Forming Networks (IFNs).

Product description

These PSPL5208 and PSPL5210 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

Where 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 models are optimized for use with different input rise times. A third IFN port is labeled “DC” and terminated in 50 Ω. A DC baseline offset, bias voltage, and/or a slower rise time, pedestal pulse may be connected to this DC port.

Typical performance

The following figure shows the PSPL5208 IFN at 20 ps/div. 5.10 V, 11.3 ps Step Input: 2 V, 50 ps Impulse and 1.3 V ptp, 13 GHz Monocycle inputs.


The following figure shows the PSPL5210 IFN at 50 ps/div. 10 V, 45 ps Step Input: 2.7 V, 50 ps Impulse and 1.7 V ptp, 6.5 GHz Monocycle inputs.
