Impedance for pass band matching¹⁾

—

Ω || pF

Output: Z_OUT= R_OUT|| C_OUT

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 #4.

important notes at the end of this document.
