After the SAW filter is removed and input impedance into the input matching / output matching 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. 3 Dec 01, 2004 SAW Components Low-loss Filter Data Sheet Characteristics Reference temperature: Terminating source impedance: Terminating load impedance: B3790 433,92 MHz TA = –40 ... +90˚C ZS = 50 Ω and matching network ZL = 50 Ω and matching network min. typ. 433,92 max. — MHz Center frequency (center frequency between 3 dB points) fC — Minimum insertion attenuation αmin (including losses in matching network) 433,86 ... 433,98 MHz Pass band (relative to αmi.
