Notes
1. Slope straight line is defined as gain at 870 MHz against gain at 45 MHz.
2. Tilt = 10.2 dB (55 to 745 MHz).
3. Tilt = 7.3 dB (55 to 547 MHz).
4. fp = 55.25 MHz; Vp = 44 dBmV;
fq = 805.25 MHz; Vq = 44 dBmV;
measured at fp + fq = 860.5 MHz.
5. 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.
6. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 35 V.
