Ω || pF

²⁾Impedance for passband matching bases on an ideal, perfect matching of the SAW filter to

source- and to load impedance (here 50 Ohm). After the SAW filter is removed and input imped-

ance into the input matching / output matching network is calculated.

The conjugate complex value of these characteristic impedances are the input and output imped-

ances for flat passband. For more details, we refer to EPCOS application note #4.
