p

fq= 403.25 MHz; Vq= 59 dBmV;
measured at fp+fq= 752.5 MHz.

2. Measured according to DIN45004B:
fp= 851.25 MHz; Vp=Vo= 59 dBmV;
fq= 858.25 MHz; Vq=Vo−6 dB;
fr= 860.25 MHz; Vr=Vo−6 dB;
measured at fp+fq−fr= 849.25 MHz.

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