The minimum of the pass band attenuation a is defined as the insertion loss a . The centre frequency f is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter min e c attenuation level relative to the insertion loss a . The nominal frequency f is fixed at 433.92 MHz without any tolerance. The given values for the relative e N attenuation a have to be achieved at the frequencies given below even if the centre frequency f is shifted due to the temperature coefficient of frequency rel c TC in the operating temperature range and due to a production tolerance for the centre frequency f . f c D a t a typ. value tolerance / limit Insertion loss a 2.6 dB max. 3.5 dB e (reference level) Nominal frequency f - 433.92 MHz N Centre frequency f 433.92 MHz - C Bandwidth BW 2 dB 700 kHz min. 400 kHz 3 dB 800 kHz min. 440 kHz 6 dB 955 kHz min. 560 kHz Relative attenuation a rel f ... f 200.00 kHz - dB max. 2.0 dB N N f 200.00 kHz ... f 220.00 kHz - dB max. 3.0 dB N N f 220.00 kHz ... f 280.00 kHz - dB max. 6.0 dB N N f - 1.0 MHz f - 5.92 MHz 17 dB min. 15 dB N N f - 5.92 MHz f - 19.92 MHz 42 dB min. 40 dB N N f - 19.92 MHz f - 423.92 MHz 55 dB min. 45 dB N N f + 1.00 MHz f + 8.00 MHz 14 dB min. 10 dB N N fN + 116.08 MHz fN + 566.00 MHz 60 dB min. 45 dB Input power level - max. 0 dBm Operating temperature range OTR - -25 +80 C Storage temperature range - -55 +125 C Frequency inversion temperature 10 C - 2 Temperature coefficient of frequency -0.04 ppm/K - TC *) f *) = Generated: Checked / Approved: Vectron International GmbH Potsdamer Strae 18 D 14 513 TELTOW / Germany Tel: (+49) 3328 4784-0 / Fax: (+49) 3328 4784-30 E-Mail: tft vectron.com Vectron International GmbH reserves the right to make changes to the product(s) and/or information contained herein without notice.
