fq= 541.25 MHz; Vq= 44 dBmV;
measured at fp+fq= 596.5 MHz.
2. Measured according to DIN45004B:
fp= 590.25 MHz; Vp=Vo;
fq= 597.25 MHz; Vq=Vo−6 dB;
fr= 599.25 MHz; Vr=Vo−6 dB;
measured at fp+fq−fr= 588.25 MHz.
3. The module normally operates at VB= 24 V, but is able to withstand supply transients up to 30 V.
