Notes

1. Slope straight line is defined as gain at 750 MHz

− gain at 45 MHz.

2. Tilt = 7.3 dB (55 to 547 MHz).

3. fp = 55.25 MHz; Vp = 44 dBmV;

fq = 691.25 MHz; Vq = 44 dBmV;

measured at fp +fq = 746.5 MHz.

4. Measured according to DIN45004B:

fp = 740.25 MHz; Vp =Vo;

fq = 747.25 MHz; Vq =Vo −6 dB;

fr = 749.25 MHz; Vr =Vo −6 dB;

measured at fp +fq − fr = 738.25 MHz.

5. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V.
