1) _{Impedance for passband matching bases on an ideal, perfect matching of the SAW filter to source- and to load}
impedance (here 50 Ohm). After removal of the SAW filter the input impedance of the input and output match-
ing network is calculated. The conjugate complex value of these characteristic impedances are the input and
output impedances for flat passband. For more details we refer to EPCOS application note #18.
