Characteristics
Remark: Reference level for the relative attenuation arel of the TFS 208K is the minimum of the pass band attenuation. Reference for the echo response attenuation is the main time response lobe, the reference time is defined as t0. The nominal frequency fN is fixed at 208 MHz without tolerance. The given values for the relative attenuation arel and for the group delay ripple have to be reached at the frequencies given below even if the centre frequency fc is shifted due to the temperature coefficient of frequency TC f in the operating temperature range and due to a production tolerance for the centre frequency fc.
