TFS220E

The TFS220E is produced by the VI telefilter. The measurement condition of this TFS220E are:(1)Ambient Temperature: 23 °C;(2)Input Power Level: 0 dBm;(3)Source impedance: 50 ;(4)Load impedance: 50 ;(5)Terminating impedances input: T.B.D.;(6)Terminating impedances output: T.B.D..

Reference level for the relative attenuation  of TFS220E arel is the minimum of the pass band attenuation amin. The minimum of the pass band attenuation amin is defined as the insertion loss ae. The nominal frequency fN is fixed to 220,38 MHz. The given values for the relative attenuation arel and for the phase ripple have to be reached at the frequencies given below also if the centre frequency fo 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 fo.

The electrical characteristics of this device can be summarized as:(1)Insertion Loss (Reference level): 6.2 dB to 10.0 dB;(2)Nominal Frequency: 220,38 MHz;(3)5 dB - Bandwidth: 1,6 MHz to 1,26 MHz;(4)Pass Band Ripple: 0.3 to 1.2 dB;(5)Group delay ripple: 0.9 us to 2.0 us;(6)Operating Temperature Range: -30 °C to +80 °C.
