Notes
1. Vo = 38 dBmV at 54 MHz; Tilt = 7.3 dB (55 to 547 MHz) extrapolated to 12 dB at 870 MHz.
2. Vo = 38 dBmV at 54 MHz; Tilt = 10.2 dB (55 to 745 MHz) extrapolated to 12 dB at 870 MHz.
3. Vo = 38 dBmV at 54 MHz; Tilt = 12 dB (55 to 865 MHz).
4. fp = 55.25 MHz; Vp = 60 dBmV; fq = 493.25 MHz; Vq = 60 dBmV; measured at fp + fq = 548.5 MHz.
5. fp = 55.25 MHz; Vp = 60 dBmV; fq = 691.25 MHz; Vq = 60 dBmV; measured at fp + fq = 746.5 MHz.
6. fp = 55.25 MHz; Vp = 60 dBmV; fq = 805.25 MHz; Vq = 60 dBmV; measured at fp + fq = 860.5 MHz.
7. Measured according to DIN45004B: fp = 540.25 MHz; Vp = Vo; fq = 547.25 MHz; Vq = Vo −6 dB; fr = 549.25 MHz;
Vr = Vo −6 dB; measured at fp + fq − fr = 538.25 MHz.
8. 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.
9. 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.
10. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V.
