Characteristics
Remark:
Reference level for the relative attenuation arel is the minimum pass band attenuation a
min
. It is defined as the insertion loss ae. The nominal
frequency fN is fixed to 380,0 MHz. The center frequency fc is the arithmetic mean value of the upper and lower frequencies at the 1 dB filter
attenuation level relative to the insertion loss ae The given values for the insertion loss, the relative attenuation arel and the group delay ripple have
to be reached at the frequencies given below also if the centre frequency fc is shifted due to the temperature coefficient of frequency TCf in the
operating temperature range and due to a production tolerance for the centre frequency fc.
