Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- Measurement condition Ambient temperature: 25 ± 5 Input power level: 5 ± 2 dBm terminating impedances Source: 220 Ω || -14.3 pF Load: 225 Ω || -13.5 pF Characteristics Remark: Reference level for the relative attenuation arel of the TFS 22.
- The centre 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 relative attenuation arel and for 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 opera.
- 8,0 dB Nominal frequency fN 228,6 MHz Relative attenuation arel kHz 0,4 dB max.
- 2 : 1 Group delay mean value fN - 665 kHz ...
- fN + 665 kHz 710 ns max. ±20 ns Group delay ripple GD fN - 665 kHz ...
- 2,5 °rms Input power level max. + 10 dBm Operating temperature range Storage temperature range Temperature coefficient TC - 18 ppm/K 1) Note 1) - ∆f (Hz) = TC (ppm/K) x (T - To) x FTo (MHz) Generated: Checked / approved: tfs228.doc Version.
Engineering review checklist
- Confirm the exact ordering code, package, pinout or terminal arrangement and document revision.
- Compare recommended operating conditions with absolute maximum ratings and retain adequate design margin.
- Validate electrical, thermal, mechanical and environmental behavior in the final application.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
