TFS 190E

      The TFS 190E has the following Measurement condition including Ambient Temperature: 23 °C;Input Power Level: 0 dBm;Terminating Impedance at fc*: input: 307 // - 12,4 pF,output: 107 // - 16,9 pF.
      The reference level for the relative attenuation arel of TFS 190E is the minimum of the pass band attenuation amin. This minimum is defined as the insertion loss ae. The nominal frequency fN is fixed at 190 MHz without any tolerance. The given values for the relative attenuation arel and 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 TCf in the operating temperature range and due to a production tolerance for the centre frequency fc.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.
      The minimum bending radius is 45 mm. The mounting surface of the filters faces the bottom side of the embossed carrier tape.Markings on the filters can be read if the upper side of the carrier tape is regarded with the sprocket holes on its right.The information provided on this page represents TI's knowledge and belief as of the date that it is provided.
