1. Measurement condition :

Ambient temperature T

Input power level:

Terminating impedances at f c *) :

2. Characteristics

Remark:

Reference level for the relative attenuation a rel of the TFS 70AA is the minimum of the pass band attenuation a min . The minimum of 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 f N is fixed at 70 MHz without tolerance.

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

*) The terminating impedances depend on parasitics and q-values of matching elements and the board used, and are to be understood as

reference values only. Should there be additional questions do not hesitate to ask for an application note or contact our design team.
