1. Measurement condition :

Ambient temperature T

Input power level:

Terminating impedances at f c *) :

2. Characteristics

Remark:

the pass band attenuation a min is defined as the insertion loss a e . The centre frequency f c is the arithmetic mean value of the upper and lower

frequencies at the 3 dB filter attenuation level relative to the insertion loss a e . The nominal frequency

The given values for the relative attenuation a rel and for the group delay ripple have to be reached at the frequencies given below also if the

centre frequency f c 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 f c .
