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.
