Notes
1. Slope straight line is defined as gain at 870 MHz against gain at 45 MHz.
2. fp = 55.25 MHz; Vp = 60 dBmV;
fq = 493.25 MHz; Vq = 60 dBmV;
measured at fp + fq = 548.5 MHz.
3. fp = 55.25 MHz; Vp = 60 dBmV;
fq = 691.25 MHz; Vq = 60 dBmV;
measured at fp + fq = 746.5 MHz.
4. fp = 55.25 MHz; Vp = 60 dBmV;
fq = 805.25 MHz; Vq = 60 dBmV;
measured at fp + fq = 860.5 MHz.
5. 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.
6. 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.
7. 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.
8. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V.
