Notes :
(1)
The customer effective impedance is : 1kΩ (real part) in parallel with a small stray capacitance (imaginary part). In
order to simplify the specification, and the measurements, only the real part is specified. The specification includes
±5% (resp. ±8%) variation on the 1kΩ for the Input (resp. Output)
(2)
Fast amplitude ripple is the difference between total amplitude ripple and amplitude variation (computed with a
second order polynomial fit within passband.)
(3)
Without losses in matching network means that the resistive part of the inductors are not considered (equivalent to
an infinite Q). For the measurements, a special calibration method will be implemented.
