The S-parameters provided in this section are based on measurements.

Measurement setup for differential in-/outputs:

In/Out

Inx/Outx

Port1

DUT

Port2

The input/output impedances are calculated from these parameters.

The impedances are given as equivalent circuit with lumped elements for differential and single ended

in-/outputs.

The high frequency in-/outputs in this section are base inputs or collector outputs.

As equivalent circuit for these in-/outputs a resistor Rp in parallel to a capacitance Cp is derived:

differential

Rpd

Cpd

The S-parameters are available on disk.
