Notes
1. Tilt = 9 dB (50 to 550 MHz); tilt = 3.5 dB at −6 dB offset (550 to 750 MHz).
2. Tilt = 12.5 dB (50 to 860 MHz).
3. fp = 55.25 MHz; Vp = 44 dBmV; fq = 805.25 MHz; Vq = 44 dBmV; measured at fp + fq = 860.5 MHz.
4. fp = 55.25 MHz; Vp = 44 dBmV; fq = 691.25 MHz; Vq = 44 dBmV; measured at fp + fq = 746.5 MHz.
5. fp = 55.25 MHz; Vp = 44 dBmV; fq = 493.25 MHz; Vq = 44 dBmV; measured at fp + fq = 548.5 MHz.
6. 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.
7. 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.
8. 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.
9. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 35 V.
