tfr433m.doc version 1.0 16.08.2002 VI TELEFILTER Measurement condition Ambient temperature: 23 Input power level: 10 Terminating Impedance at fc*: for input: 50 for output: 50 °C dBm Ω || 0 pF Ω || 0 pF SAW Resonator Specification TFR 433M 1/5 Characteristics Remark: The minimum of the pass band attenuation amin is defined as the insertion loss ae. The centre frequency fc is the frequency of the minimum of the passband attenuation amin. The tolerance for the resonant frequency also includes a centre frequency shift due to the temperature coefficient of frequency TCf in the operating temperature range and a production tolerance for the resonant frequency fR.
