Notes
1. Decrease per octave of 1.5 dB.
2. Vp = 59 dBmV at fp = 349.25 MHz;
Vq = 59 dBmV at fq = 403.25 MHz;
measured at fp + fq = 752.5 MHz.
3. Measured according to DIN45004B:
fp = 341.25 MHz; Vp = Vo;
fq = 348.25 MHz; Vq = Vo −6 dB;
fr = 350.25 MHz; Vr = Vo −6 dB;
measured at fp + fq − fr = 339.25 MHz.
4. Measured according to DIN45004B:
fp = 851.25 MHz; Vp = Vo;
fq = 858.25 MHz; Vq = Vo −6 dB;
fr = 860.25 MHz; Vr = Vo −6 dB;
measured at fp + fq − fr = 849.25 MHz.
5. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V.
